Site to SIte VPN through a NAT device

I, i am having some trouble running a site to site vpn between two 3725 routers running c3725-advsecurityk9-mz124-15T1 which i hope i can get some help with, i am probably missing something here. The VPN ran fine when both VPN routers were connected directly to the internet and had public IPs on the WAN interfaces, but i have had to move one of the firewalls inside onto a private IP. The setup is now as below
VPN router A(192.168.248.253)---Company internal network----Fortigate FW-----internet----(217.155.113.179)VPN router B
Now the fortigate FW is doing some address translations
- traffic from 192.168.248.253 to 217.155.113.179 has its source translated to 37.205.62.5
- traffic from 217.155.113.179 to 37.205.62.5 has its destination translated to 192.168.248.253
- The firewall rules allow any traffic between the 2 devices, no port lockdown enabled.
- The 37.205.62.5 address is used by nothing else.
I basically have a GRE tunnel between the two routers and i am trying to encrypt it.
Router A is showing the below

I can see the counters incrementing over the ACL on both routers so i know GRE traffic is interesting.
Here are some debugs too

AAA Accounting through a NAT device

Good Day to you all,
I am trying to configure aaa accounting through a natted device to a ACS 4.0 server. the information is logged ok but is logged as the device that is performing the natting. is there a way to configure aaa accounting to show the acctual device being updated in the ACS logs

Assuming its RADIUS...
Is it possible to get the originating device to include the NAS-IP-Address or NAS-Identifier attributes in the accounting records?
This will be the actual device values rather than the peer address of the NAT device.

How to access the gui through a NAT device

Hi
I have to access the management GUI over a NAT IP. So the browser is not accessing the configured managment IP. How can this be realized?
Unfortunately the programmers wrote the HTML code with absolute addressed links instead of using relative links.
Example HTML code excerpt from the web gui:
<script src="
https://wsa.test.local:8443/scfw/1y-7.1.2-020/yui/animation/animation-min.js"></script>
Good code shoul read like:
<script src="/scfw/1y-7.1.2-020/yui/animation/animation-min.js"></script>
The second code doesn't take care on which hostname/IP nor port the web gui is seen from the client. The browser just adds hostname to the beginning of the URL as it was used to access the starting page. So a NAT or even PAT on the way to access the box has no influence on the usability.
Any ideas how to circumvent that problem?

We found out that this seems to be a limitation of the browser. It doesn't work with iE 8/9 but it works with Firefox 6.0.1.
Strange...

IPsec VPN behind a NAT devices

Thanks but just resolved the problem. Thus i deleted my posting.

Thank you for you replies there are 2 options either easy vpn client but it requires cisco at the other end ...or that one:
crypto keyring spokes
pre-shared-key address 0.0.0.0 0.0.0.0 key cisco123
crypto isakmp profile L2L
description LAN-to-LAN for spoke router(s) connection
keyring spokes
match identity address 0.0.0.0
here is the cisco url link where u can find further information about it:
http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a00801dddbb.shtml
I m gonna test those 2 options
I still don t know how to push acl with easy vpn client and remote mode.
thank you for your advices

TACACS+ requests through NAT device

Hi everyone.
I want to Authenticate and Authorize VTY-Access to Cisco devices using TACACS+. The config is pritty "straight forwasrd", BUT:
I want to forward the TACACS+ Request through a NAT device and on to the "Internet" where the TACAS+ server is located. (ACS 3.3)
2 Questions in this situation appeares:
- Does TACACS+ protocol support request through NAT devices?
- Is it possible to connect different devices begind the NAT device, using only one Outside NAT IP address? (Using the same secret key for all aaa-clients and on the ACS)
As you see, i want to connect "as many aaa-clients as possible" to a TACACS+ Server with "as easy = less configuration changes, as possible" .
I know VPN's are options as well, but it is not prefered in my design.
Best Regards
Jarle Steffensen

As far as I know what you propose will work. You are the only one who knows what the local environment is and what the real requirements are and you must decide whether it is a good idea to do it this way.
I do not see why passing the TACACS request through a NAT device would impact it, so long as the NAT was static or an overload (PAT). The request needs to get to the TACACS server with a consistent source address. If it was a dynamic NAT and one request came with one source address and the next request came with a different source address, it would only work if the TACACS server was configured with ALL of the possible translated addresses. (and part of your requirement is to simplify the config not to complicate it).
If there are multiple devices sending requests to TACACS through the NAT device, it would look to the TACACS server as if there were a single remote device with lots of users. If you do not care that the TACACS server can not differentiate the remote devices then your solution should work. Do you want to be able to look at the TACACS reports and see that this successful (or that unsuccessful) attempt came from this machine or that machine? If you do not care then your solution should work. If you do care to differentiate the remote activity then you need a solution like VPN which maintains the individuality of the remote devices.

Site to Site and Remote Access VPN

Hi All,
Is it possible to configure Site to Site and Remote Access VPN on same interface of Cisco ASA 5505 ?
Regards
Abhishek
This topic first appeared in the Spiceworks Community

A document exists where PIX/ASA maintains LAN-ti-LAN IPsec tunnel at two end points and there is overlapping networks at ther inside interface of both the asa. Probably, the basic configuration for both asa and IOS routers are nat config. So, this particular document might be useful for your requirement
PIX/ASA 7.x and later: Site to Site (L2L) IPsec VPN with Policy NAT (Overlapping Private Networks) Configuration Example

ASA 5505 site to site VPN from a device 7.2 to a device 8.2

I'm trying to make some test with two ASA 5505; one has software version 7.2(4) the other 8.2.
I would like to make a sit to site VPN from the two device.
I followed the VPN site to site wizard on both machine with the correct parameters, but it does'n work.
Is it possible to make this kind of VPN between devices with different Software version? Or I should upg the older with 7.2 to 8.2 before ?
Thank for your help.
Marco

Tks Soeren for your help, these are some info about my test:

ASA 5505: Site-to-Site VPN, NAT (Overlap Subnets)

Greetings all. I've searched through the forums and have found some similar situations to mine but nothing specific. I'm hoping this is an easy fix... :/
I volunteer for a non-profit medical facility that has an ASA 5505 (v8.4). They needed a site-to-site VPN to another facility (a Fortinet w/ 10.10.115.0/24) to securly transfer digital X-Ray images. Very simple setup... the issue is, my 5505 (192.168.1.x) overlaps with another site-to-site VPN connection on the Fortinet side already. So...
The network admin on the Fortinet side assinged me 172.31.1.0/24. I have established a connection but obviously, cannot route anywhere to the other side. Anyone have any suggestions here, how I might be able to accomplish this - hopefully with a simple NAT setup?
Thank you in advance everyone.

Hello Chris,
For this scenario you will need to create a Policy-NAT rule and then configure the Interesting Traffic with the translated IP address.
Basically the NAT configuration will be like this:
object network Local-net
subnet 192.168.1.0 255.255.255.0
object network Translated-net
subnet 172.31.1.0 255.255.255.0
object network Fortinet-net
subnet 10.10.115.0 255.255.255.0
nat (inside,outside) source static Local-net Translated-net destination static Fortinet-net Fortinet-net
Obviously, you can change the name of the objects.
Then in the interesting traffic, the ACL that is apply in the crypto map that defines the VPN traffi, you will need to configure it like this:
access-list anyname permit ip 172.31.1.0 255.255.255.0 10.10.115.0 255.255.255.0
This should allow you to pass traffic over this tunnel and it will hide your network behind the network that the Fortinet assigned you.
Let me know if you have any doubts.

ASA Cannot access https device via Clientless VPN bookmark, site to site works fine

We've got two offices connected via an IPSEC tunnel. This site to site VPN works great, we can access our remote devices fine from a PC on either LAN at each office. The device's address is https://192.168.210.2
However, if we make a bookmark on the Clientless VPN for that same address the conneciton just times out if it has to go over the site to site VPN.
We plugged the exact same web enabled device on the local side of the VPN, put in a bookmark for its https address and it works fine. Its just remote bookmarks for devices on the other side of the tunnel do not work.
Looking at the debug log I see the request going out from the source to the destination on port 443 but nothing more. The NAT exemption etc are all right because people on the LAN have no problem accessing this device remotely with their browser.
I haven't been able to adequately describe this problem to find a matching Cisco example, anyone know how to fix this?

hi luis,
thank you for your reply. we've checked the smoothwall configuration, but couldn't discover anything which could cause this problem. we even tried replacing the sa520 with a draytek vigor router to set up an lan-to-lan vpn with the smoothwall. with the draytek in place we have no problems accessing the aforementioned servers, so it seems the issue is with the SA520.
what exactly do you mean by creating an ACL from the remote WAN to our LAN? i assumed you meant creating a firewall rule, allowing traffic from the remote device's public ip to our LAN. however, in that case i need to enter an ip address of a device in our LAN, or else i cannot save this rule. as a test i entered the ip address of my machine as the destination address, but am still unable to access the aforementioned servers.
here's how i set up the rule:
from zone: UNSECURE (WAN/optional WAN)
to zone: LAN
service: ANY
action: ALLOW always
schedule: (not set)
source hosts: Single address
from: public ip of one of the aforementioned servers
source NAT settings > external IP address: WAN interface address (cannot change this setting)
source NAT settings >WAN interface: dedicated WAN (cannot change this setting)
destination NAT settings > internal ip address: 192.168.11.123 (ip address of my machine)
enable port forwarding: unchecked
translate port number: empty
external IP address: dedicated WAN

Targeted HTTP Requests through SonicWALL Site-to-Site VPN

I have a B2B tunnel to one of our customers. All HTTP/HTTPS traffic from our main office for those addresses goes across the B2B.Now, I have a remote office connected to the main office via site-to-site VPN. How can I target HTTP/HTTPS requests for only the customer websites to use the site-to-site VPN to our office, then the B2B, while allowing other Web traffic to go straight out through the remote office? I have already added the subnets used by the B2B to the access lists at both ends of the site-to-site, but computers at the remote office cannot load Web pages, because the requests are not coming from our B2B IP address. nslookup and ping work from the remote office; DNS is resolving the name to the correct IP address. However, the HTTP/HTTPS requests are going straight out through the remote office firewall without hitting the...

Hi
I looked through the similar questions and I cannot find the answer. My VPN is working correctly and I can ping every LAN interface address objects specified in my routes but I'm unable to ping or access end devices beyond that. IPS and the GAV is not enable since I don't have the licenses, so theirs no concern there. Something is telling me that it could be a basic route needs to be in place on VPN > LAN but that was created in the initial VPN configuration.
For example I can ping Remote LAN interfaces 172.16.0.254, 172.18.0.254 but I cant ping the devices in those subnets.

Cisco ASA Site to Site IPSEC VPN and NAT question

Hi Folks,
I have a question regarding both Site to Site IPSEC VPN and NAT. Basically what I want to achieve is to do the following:
ASA2 is at HQ and ASA1 is a remote site. I have no problem setting up a static static Site to Site IPSEC VPN between sites. Hosts residing at 10.1.0.0/16 are able to communicate with hosts at 192.168.1.0/24, but what i want is to setup NAT with IPSEC VPN so that host at 10.1.0.0/16 will communicate with hosts at 192.168.1.0/24 with translated addresses
Just an example:
Host N2 (10.1.0.1/16) will communicate with host N1 192.168.1.5 with destination lets say 10.23.1.5 not 192.168.1.5 (Notice the last octet should be the same in this case .5)
The same translation for the rest of the communication (Host N2 pings host N3 destination ip 10.23.1.6 not 192.168.1.6. again last octet is the same)
It sounds a bit confusing for me but i have seen this type of setup before when I worked for managed service provider where we had connection to our clients (Site to Site Ipsec VPN with NAT, not sure how it was setup)
Basically we were communicating with client hosts over site to site VPN but their real addresses were hidden and we were using translated address as mentioned above 10.23.1.0/24 instead of (real) 192.168.1.0/24, last octet should be the same.
Appreciate if someone can shed some light on it.

Hi,
Ok so were going with the older NAT configuration format
To me it seems you could do the following:
Configure the ASA1 with Static Policy NAT
access-list L2LVPN-POLICYNAT permit ip 192.168.1.0 255.255.255.0 10.1.0.0 255.255.0.0
static (inside,outside) 10.23.1.0 access-list L2LVPN-POLICYNAT
Because the above is a Static Policy NAT it means that the translation will only be done when the destination network is 10.1.0.0/16
If you for example have a basic PAT configuration for inside -> outside traffic, the above NAT configuration and the actual PAT configuration wont interfere with eachother
On ASA2 side you can normally configure NAT0 / NAT Exemption for the 10.1.0.0/16 network
access-list INSIDE-NONAT remark L2LVPN NONAT
access-list INSIDE-NONAT permit ip 10.1.0.0 255.255.0.0 10.23.1.0 255.255.255.0
nat (inside) 0 access-list INSIDE-NONAT
You will have to take into consideration that your access-list defining the L2L-VPN encrypted traffic must reflect the new NAT network
ASA1: access-list L2LVPN-ENCRYPTIONDOMAIN permit ip 10.23.1.0 255.255.255.0 10.1.0.0 255.255.0.0
ASA2: access-list L2LVPN-ENCRYPTIONDOMAIN permit ip 10.1.0.0 255.255.0.0 10.23.1.0 255.255.255.0
I could test this setup tomorrow at work but let me know if it works out.

Azure multiple site-to-site VPNs (dynamic gateway) with Cisco ASA devices

Hello
I've been experimenting with moving certain on-premise servers to Azure however they would need a site-to-site VPN link to our many branch sites e.g. monitoring of nodes.
The documentation says I need to configure a dynamic gateway to have multiple site-to-site VPNs. This is not a problem for our typical Cisco ISR's. However three of our key sites use Cisco ASA devices which are listed as 'Not Compatible' with dynamic routing.
So I am stuck...
What options are available to me? Is there any sort of tweak-configuration to make a Cisco ASA work with Azure and dynamic routing?
I was hoping Azure's VPN solution would be very flexible.
Thanks

Hello RTF_Admin,
1. Which is the Series of CISCO ASA device you are using?
Thank you for your interest in Windows Azure. The Dynamic routing is not supported for the Cisco ASA family of devices.
Unfortunately, a dynamic routing VPN gateway is required for Multi-Site VPN, VNet to VNet, and Point-to-Site.
However, you should be able to setup a site-to-site VPN with Cisco ASA 5505 series security appliance as demonstrated in this blog:
Step-By-Step: Create a Site-to-Site VPN between your network and Azure
http://blogs.technet.com/b/canitpro/archive/2013/10/09/step-by-step-create-a-site-to-site-vpn-between-your-network-and-azure.aspx
You can refer to this article for Cisco ASA templates for Static routing:
http://msdn.microsoft.com/en-us/library/azure/dn133793.aspx
If your requirement is only for Multi-Site VPN then there is no option but to upgrade the device as Multisite VPN requires dyanmic routing and unfortunately there is no tweak or workaround due to hardware compatibility issue.
I hope that this information is helpful
Thanks,

RV042 Site-to-Stie VPN with NAT on one side

I set up a site-to-site VPN using two RV042s some time ago. One was behind a NATting router. The other was the internet interface itself.
Somewhere I had found a paper describing how to do this. It said that only ONE of them could be behind another NATting router. So, that's how this was set up. I sure wish I could find that paper again!!! Any suggestions?
Now I have to do the same thing again but can't get it working. It looks like this:
RV042 VPN public address <> cable modem <> internet <> RV042 "firewall" with IPSEC passthrough enabled <> interim subnet LAN <> RV042 VPN <> LAN
I'm getting log messages and on the remote site log (the left side of the above) like:
initial Aggressive Mode packet claiming to be from [xxx.xxx.xxx.xxx] on [same] but no connection has been authorized
and
No suitable connection for peer '10.98.76.2', Please check Phase 1 ID value
(where 10.98.76.2 is the IP address of the RV042 WAN port on the interim subnet)
I have them both in Aggressive mode as eventually I'll be using a dyndns url. But, for now, I'm using the actual IP addresses so that should not be an issue one way or the other..

make sure the configuration u do on both the side should be same....and secondly exempt the NAT rules then only it will work.

Setting up Site-to-Site VPN and nat on IOS

I have a senario I am looking to setup. I have a Cisco 3825 router that handles roughly 50 site-to-site VPN's. I have a particular VPN where I would like to nat (actually overload) off an interface for a specific VPN site-to-site tunnel. I know when you are doing nat you of course have an inside and an outside interface which I do on the router but how would you overload (pat) on an interface for just a specific VPN tunnel? Say you wanted to overload your entire internal supernet to a single private (RFC 1918) interface addess? Typically the outside interface (nat outside) what you would overload off of has a public ip address, but in this case you want to use a private RFC 1918 address as the source of the overload interface?
Any help is appreciated.

hi ,
did you think of using a normal statment and use a route map with that statment that only permit the VPN traffic to be natted using that statment and deny any other translation , and for the crypto access-list you should use the source as the pattted ip address and the destination as the the remote proxies .
regards.

Setting up site to site vpn with cisco asa 5505

I have a cisco asa 5505 that needs to be set up for site to site vpn to a cisco asa 5500. The 5505 is the remote office and the 5500 is the main office.
IP of remote office router is 71.37.178.142
IP of the main office firewall is 209.117.141.82
Can someone tell me if my config is correct, this is the first time I am setting this up and it can not be tested until I set it up at the remote office. I would rather know its correct before I go.

Hi Mandy,
By using following access list define Peer IP as source and destination
access-list outside_1_cryptomap extended permit ip host 71.37.178.142 host 209.117.141.82
you are not defining the interesting traffic / subnets from both ends.
Make some number ACL 101 as you do not have to write the extended keyword then if you like as follows, or else NAME aCL will also work:
access-list outside_1_cryptomap extended ip 192.168.200.0 0.0.0.255 192.168.100.0 0.0.0.255
access-list outside_1_cryptomap extended ip 192.168.200.0 0.0.0.255 192.168.100.0 0.0.0.255
access-list 101 remark CCP_ACL Category=4 access-list 101 remark IPSEC Rule
!.1..source subnet(called local encryption domain) at your end 192.168.200.0
!..2.and destination subnet(called remote encryption domain)at other end 192.168.100.0 !.3..I mean you have to define what subnets you need to communicate between which are behind these firewalls
!..4...Local Subnets behind IP of the main office firewall is 209.117.141.82 say
!...at your end 192.168.200.0
!..5.Remote Subnets behind IP of remote office router is 71.37.178.142 say
!...at other end 192.168.100.0
Please use Baisc Steps as follows:
A. Configuration in your MAIN office having IP = 209.117.141.82 (follow step 1 to 6)
Step 1.
Define Crypto ACL/ mirror ACL for other end (change source to destination and destination to source in other side router or VPN device and thats why they are called mirror ACL/ or also called Proxy ID or also called Proxy ACL, your interesting traffic , that you want to encrypt / trave/enter in the tunnel)
access-list outside_1_cryptomap extended ip 192.168.200.0 0.0.0.255 192.168.100.0 0.0.0.255
Step 2.
Config ISAKMP Policy with minimum 4 parameters are to be config for
crypto isakmp policy 10
authentication pre-share ---> Ist parameter of setting Authentication type ISAKMP Policy is OK
encryption aes-256   --->2nd parameter of ISAKMP Policy is OK
hash sha   ---> 3rd parameter of ISAKMP Policy is OK
group 5 ---> 4th parameter of ISAKMP Policy is OK
lifetime 86400 ------ > this 5th parameter is optional , and will negotiate for the less value at either end or by default is will be taken 86400
Step 3.
Define Preshared key or PKI which you will use with other side Peer address 71.37.178.142, either key type 0 is Plain text anyone can see it over internet, or use key type 6 for encrypted key , say your password is CISCO123
Here in your case in step 2 Authentication is using PSK, looks you have not defines Password
Use following command:
crypto isakmp key 0 CISCO123 address 71.37.178.142
or , but not both
crypto isakmp key 6 CISCO123 address71.37.178.142
step 4.
Define Transform set , which will be used for phase 2 tunnel parameters, if you use ESP it can have to sets one cor encryption and other for Authentication.
Here is yours one:
crypto ipsec transform-set ESP-AES-256-SHA esp-aes-256 esp-sha-hmac
this is correct but give name somthing easier to remember /distinguish it is a transform set , like TSET1 instead of ESP-AES-256-SHA ,try following (here you are using ESP so for encryption we use first set as esp-des and for authentication we use second set esp-sha-hmac)
crypto ipsec transform-set TSET1 esp-des esp-sha-hmac
or
crypto ipsec transform-set TSET1 esp-aes-256 esp-sha-hmac
Suppose you are using only AH then as AH does not support encryption or confidentiality hence it always use onle one set not 2 sets like ESP(remember the difference) say for example only one set for auth etc but no set for encryption hence AH have no such sets like ah-des or ah-3des or ah-aes, it has only second set for authentication like
ah-sha-hmac or ah-md5-hmac
crypto ipsec transform-set TSET1 ah-sha-hmac
or
crypto ipsec transform-set TSET1 ah-md5-hmac
Step 5.
Now configure Crypto MAP as follows and only one CMPA can be applied to OUTSIDE Interface as VPN tunnel is alsways applied for traffic from inside subnets to outside subnets and only once Cryptomap can be applied to OUTSIDE Interface and hence for several VPN peers from different vendors we use seq no 10, 2 30 for different tunnels in one single CMAP:
crypto map ipsec-isakmp
1. Define peer -- called WHO to set tunnel with
2. Define or call WHICH - Transform Set
3. Define WHAT to call interesting traffic define in your ACL or Proxy ID or Proxy ACL in step 1 using match address
Like in your case it is but ipsec-isakmp keyword missing in the ;ast
crypto map outside_map 10 ipsec-isakmp
1. set peer 209.117.141.82 -----> is correct as this is your other side peer called WHO in my step
2. set transform-set TSET1 -----> is correct as this is WHICH, and only one transform set can be called
!..In you case it is correct
!...set transform-set ESP-AES-256-SHA (also correct)
3. match address outside_1_cryptomap ---->Name of the extended ACL define as WHAT to pass through this tunnel
4. set pfs group5 (this is optional but if config at one end same has to be config at other side peer as well)
Step 6.
Now apply this one crypto MAP to your OUTSIDE interface always
interface outside
crypto map outside_map
Configure the same but just change ACL on other end in step one by reversing source and destination
and also set the peer IP of this router in other end.
So other side config should look as follows:
B. Configuration in oyur Remote PEER IP having IP = 71.37.178.142 (follow step 7 to 12)
Step 7.
Define Crypto ACL/ mirror ACL for other end (change source to destination and destination to source in other side router or VPN device and thats why they are called mirror ACL/ or also called Proxy ID or also called Proxy ACL, your interesting traffic , that you want to encrypt / trave/enter in the tunnel)
access-list outside_1_cryptomap extended ip 192.168.100.0 0.0.0.255 192.168.200.0 0.0.0.255
Step 8.
Config ISAKMP Policy with minimum 4 parameters are to be config for
crypto isakmp policy 10
authentication pre-share ---> Ist parameter of setting Authentication type ISAKMP Policy is OK
encryption aes-256   --->2nd parameter of ISAKMP Policy is OK
hash sha   ---> 3rd parameter of ISAKMP Policy is OK
group 5 ---> 4th parameter of ISAKMP Policy is OK
lifetime 86400 ------ > this 5th parameter is optional , and will negotiate for the less value at either end or by default is will be taken 86400
Step 9.
Define Preshared key or PKI which you will use with other side Peer address key type 0 is Plain text anyone can see it over internet, or use key type 6 for encrypted key , say your password is CISCO123
Here in your case in step 8 Authentication is using PSK, looks you have not defines Password
Use following command:
crypto isakmp key 0 CISCO123 address 209.117.141.82
or , but not both
crypto isakmp key 6 CISCO123 address 209.117.141.82
step 10.
Define Transform set , which will be used for phase 2 tunnel parameters, if you use ESP it can have to sets one cor encryption and other for Authentication.
Here is yours one:
crypto ipsec transform-set ESP-AES-256-SHA esp-aes-256 esp-sha-hmac
this is correct but give name somthing easier to remember /distinguish it is a transform set , like TSET1 instead of ESP-AES-256-SHA ,try following (here you are using ESP so for encryption we use first set as esp-des and for authentication we use second set esp-sha-hmac)
crypto ipsec transform-set TSET1 esp-des esp-sha-hmac
or
crypto ipsec transform-set TSET1 esp-aes-256 esp-sha-hmac
Suppose you are using only AH then as AH does not support encryption or confidentiality hence it always use onle one set not 2 sets like ESP(remember the difference) say for example only one set for auth etc but no set for encryption hence AH have no such sets like ah-des or ah-3des or ah-aes, it has only second set for authentication like
ah-sha-hmac or ah-md5-hmac
crypto ipsec transform-set TSET1 ah-sha-hmac
or
crypto ipsec transform-set TSET1 ah-md5-hmac
Step 11.
Now configure Crypto MAP as follows and only one CMPA can be applied to OUTSIDE Interface as VPN tunnel is alsways applied for traffic from inside subnets to outside subnets and only once Cryptomap can be applied to OUTSIDE Interface and hence for several VPN peers from different vendors we use seq no 10, 2 30 for different tunnels in one single CMAP:
crypto map    ipsec-isakmp
1. Define peer -- called WHO to set tunnel with
2. Define or call WHICH - Transform Set, only one is permissible
3. Define WHAT to call interesting traffic define in your ACL or Proxy ID or Proxy ACL in step 1 using match address
Like in your case it is but ipsec-isakmp keyword missing in the ;ast
crypto map outside_map 10 ipsec-isakmp
1. set peer 209.117.141.82 -----> is correct as this is your other side peer called WHO in my step
2. set transform-set TSET1 -----> is correct as this is WHICH, and only one transform set can be called
!..In you case it is correct
!...set transform-set ESP-AES-256-SHA (also correct)
3. match address outside_1_cryptomap ---->Name of the extended ACL define as WHAT to pass through this tunnel
4. set pfs group5 (this is optional but if config at one end same has to be config at other side peer as well)
Step 12.
Now apply this one crypto MAP to your OUTSIDE interface always
interface outside
crypto map outside_map
Now initite a ping
Here is for your summary:
IPSec: Site to Site - Routers
Configuration Steps
Phase 1
Step 1: Configure Mirrored ACL/Crypto ACL       for Interesting Traffic
Step 2: Configure ISAKMP Policy
Step 3: Configure ISAKMP Key
Phase 2
Step 4: Configure Transform Set
Step 5: Configure Crypto Map
Step 6: Apply Crypto Map to an Interface
