OSPF Route v IPSEC VPN
Hello all.
Could anyone point me in the right direction regarding the dilema below.
I have a pair of ASA 5510's running with VLAN Sub-interfaces. For simplicity i'm going to label them 1.3 (192.168.12.0/24) and 1.16 (172.16.100.0/24)
Connected to VLAN.3 is a 2801 Router that is advertising an OSPF route to 172.20.0.0/16 via 192.168.12.253 (MPLS network). I can see this in the routing table on the ASA.
However, I have to configure a new Site-to-Site VPN for a client on VLAN16, which as it would happen, use 172.20.0.0/16 at the remote end. The local networks are segregated and I do not have the 'Same Sec permit' enabled.
When I run a packet tracer from the VLAN16 Network, to 172.20.0.0/16 I can see its trying to egress out of 192.168.12.253.
The million dollar question is am I able to get this Site-to-site to 'ignore' the entry in the routing table and go out via the 'Outside' interface?
You can probably tell I'm a total novice so any assistance would be appreciated.
Thanks.
You would probably get a better response if you post this on the security forum.
I think your only option is to either perform desitnation NAT or have the remote end do the natting from their end in order to prevent the overlap.

Does 1841 router support IPsec vpn?
Hi,
how can i check if my router supports IPsec VPN?
Cisco 1841 Software (C18410IPBASEK9-M), 12.4(11)T

kimhoeHi,
Yes, it does support IPSEC VPN. You can check it from software adviser tool at Cisco site,

Hello,
i try to setup a IPSEC VPN (Site-by-Site or if not possible Client-BySite) between a Netgear Pro Safe Router and Windows Server 2012.
The Problem: Tunnel is up and running, but no Ping, no traffic at all.
the Server 2012 uses HyperV and has one hardware-NIC with public ip, lets say 123.123.123.1.
if no site-by-site is possible in my situation with built-in-tools this server would be only a client-site which would "dial-up" to the netgear box.
the server has a second virtual NIC with IP 192.168.137.1. Routing and RAS is enabled, because there are two virtual other servers whichs has 192.168.137.2 and 192.168.137.3.
The Netgear-ProSafe has public ip 122.122.122.1 and LAN-Subnet 192.168.21.0/24.
I created the Tunnel in the Advanced-Firewall-Options-Window. Both, Windows and the Router, say, the VPN-Tunnel is okay. Also, i can see ESP-Packets with wireshark.
If i ping (from router to server and other direction) i get no response. Some people said, the RAS itselfe could not accept packages, but i tried from one of the virtual clients also (192.168.137.2) and no ping there also.
i tried to add a route for subnet 192.168.21.0 with 192.168.137.1 as gateway but that didn't helped also.
now, after all this time i spend today to this problem i'm a bit confused.
as i know vpn-connections there are always virtual devices, and routes for the vpn-subnets assigned to this device.
the windows firewall does not create any device, and it does not create any route - i suppose, this is because "routing and ras or windows firewall-service" does this work "internally". is that correct? do i need any routes?
i was wondering why the ICMP packet from my ping in wireshark had the public ip as source (123.123.123.1) and not the "internal" 192.168.137.1 - and i tried to restrict the vpn-rule only for the virtual internal NIC but this isn't possible, as
it is no option inside the gui.
it would be great if somebody could explain me how config and packages SHOULD look....i've never used the built-in vpn/ipsec/ras services before, so i don't know how things has to be for a correct working environment. also, i need a solution and any help
to solve the problem would be great also!
now i try to sleep one night - maybe i get some nice idea after some hours of sleeping. good night.
Addition: After some more tests i find out that if i change the local endpoint (endpoint 1) from the virtual network (192.168.137.0/24) to the public ip of the server (123.123.123.1) inside the tunnel-rule and inside the vpn-policy of the router i can access
the netgear and other devices in the remote-network 192.168.21.0 over this ip-adresses. ping is not working, but other things seems to work fine. i want to be able to ping as well ofcourse and this wired configuration looks wrong to me...can some network-professional
help out with an explanation?
Second Addition: I can set the Local Endpoint also to "any" and it does work - but ping still does not work :-(
Third Addition: The Ping does work if i disable the NAT-Functionality on the Physical NIC. ....mhm.....I would definitly recommend the usage of a virtual router instead using windows onboard-firewall to make the site-to-site tunnel!
as you can see in my linked thread above (Link)
this scenario is not supported from microsoft! you will run into problems!
we do run a hyperv virtual machine and install the wonderful distribution pfsense inside this box. pfsense is a software-linux-router with ipsec-functionality, which works like a charm!
and by the way i recommend to not use the products of netgear! they are expensive, very slow and the service is not good!
we have good experience with Vigor-Routers! They are less expensive, the Service is very good, and the devices are much faster, AND! ...the vpn-connections stay stable up!
this experience was very time-intensive to make! hope this will help someone else in the future. -
ASA 5505 IPSEC VPN connected but can't access to LAN
ASA : 8.2.5
ASDM: 6.4.5
LAN: 10.1.0.0/22
VPN Pool: 172.16.10.0/24
Hi, we purcahsed a new ASA 5505 and try to setup IPSEC VPN via ASDM; i just simply run the Wizards, setup vpnpool, split tunnelling,etc.
I can connect to the ASA by using cisco VPN client and internet works fine on the local PC, but it cannot access to the LAN (can't ping. can't remote desktop). I tried the same thing on our Production ASA(those have both Remote VPN and Site-to-site VPN working), the new profile i created worked fine.
Below is my configure, do I mis-configure anything?

: endI change a Machine's gateway to this ASA and capture again, now we can see some reply.
All ohter PCs and switches gateway are point to another ASA, maybe that's the reason why i didn't work?
what's the recommanded way to make our LAN to have two 2 gateways(for load balance or backup router, etc)?
add two gateways to all PCs and swtichwes?

Cisco Jabber Client for Windows 9.7 Can't Connect to Other IPSec VPN Clients Over Clustered ASAs
Environment:
2 x ASA 5540s (at two different data centers) configured as a VPN Load Balancing Cluster
Both ASAs are at version 8.4(5)6
IPSec VPN Client version: 5.0.07.440 (64-bit)
Jabber for Windows v9.7.0 build 18474
Issue:
If I am an IPSec VPN user…
I can use Jabber to another IPSec VPN user that is connected to the same ASA appliance.
I can’t use Jabber to another IPSec VPN user that is connected to the different ASA appliance that I am connected to.
In the hub-and-spoke design, where the VPN ASA is a hub, and the VPN client is a spoke; if you have two hubs clustered together, how does one spoke communicate with another spoke on the other hub in the cluster? (How to allow hairpinning to the other ASA)Portu,
Thanks for your quick reply.
Unfortunately, I do not have access to the ASA logs nor would I be permitted to turn on the debug settings asked for above. I might be able to get the logs but it will take awhile and I suspect they wouldn't be helpful as this ASA supports thousands of clients, therefore, separating out my connection attempts from other clients would be difficult.
I can, though, do whatever you want on the Linux router. Looking over the firewall logs at the time of this problem, I don't see anything that looks suspicious such as dropped packets destined for the Windows client.
As I said in my original post, I'm not a networking expert - by any means - but I am willing to try anything to resolve this. (But I might need a bit of handholding if I need to set up a wireshark andor tcpdump.)
Thanks again. -

IPSEC VPN clients can't reach internal nor external resources
Hi!
At the moment running ASA 8.3, with fairly much experience of ASA 8.0-8.2, I can't get the NAT right for the VPN clients.
Im pretty sure it's not ACL's, although I might be wrong.
The problem is both VPN users can reach internal resources, and vpn users cant reach external resources.
# Issue 1.
IPSEC VPN client cannot reach any local (inside) resources. All interfaces are pretty much allow any any, I suspect it has to do with NAT.
When trying to access an external resource, the "translate_hits" below are changed:

1 (outside) to (outside) source dynamic vpn_nat interface
translate_hits = 37, untranslate_hits = 11
When trying to reach a local resource (10.0.0.0/24), the translate hits below are changed:
5 (inside) to (outside) source static any any destination static NETWORK_OBJ_172.16.32.0_24 NETWORK_OBJ_172.16.32.0_24
translate_hits = 31, untranslate_hits = 32

pre-shared-key *****Hi,
I don't seem to get a reply from 8.8.8.8 no, kind of hard to tell as it's an iphone. To me, all these logs simply says it works like a charm, but still I can get no reply on the phone.

Cisco IPSec VPN Client and sending a specific Radius A-V value to ACS 5.2
This setup is to try routing Cisco VPN to either RSA or Entrust from Cisco ACS 5.2, depending on some parameter in incoming AUTH request from Cisco IPSec VPN Client 5.x. Tried playing with pcf files and user names/identity stores, none seems working
Hi Tony,
to the best of my knowledge this is currently not possible, but will be once this enhancement is implemented:
CSCsw31922 Radius upstream VSAs (Tunnel Group,Client type) for VPN policy decisions
You may want to try and ask in the AAA forum if there is anything you can do on ACS...

ASA IPSEC VPN Design Question; ARP Between ASA
I"ve a requirement to put two ASA between two sites. The second site has hosts within the same network as the first site (conflict of fundamental routing principles). Can you put an ASA inline between the router and distribution switch at each site, setup an IPSEC VPN and not have issue? I thought we could have the distro switch terminate in the DMZ interface setup as a layer 2 interface in a vlan with a vlan int in the same network as the vlan int on the ASA DMZ interface on the ASA at the other site. Will this work? I guess the biggest concern is how to get layer 2 (arp) to work so hosts/servers can find each other between buildings and not get dropped on a layer 3 interface that doesn't see the distant network on a different egress interface.
Thanks!
MattMatt,
AFAIK - what you are describing is layer 2 tunneling, providing layer 2 networks from two speperate locations.
The only way I am aware of how to provide this - does NOT invlove ASA's or VPN's suing layer 3. You could do this over MPLS or a transparent layer 2 pt-pt circuit.
Perhaps another netpro has done this or knows how - I did hear of someone bridging thru a GRE tunnel, not sure if that is a viable option or actually works.

Setting up IPsec VPNs to use with Cisco Anyconnect
So I've been having trouble setting up vpns on our ASA 5510. I would like to use IPsec VPNs so that we don't have to worry about licensing issues, but from what I've read you can do this with and still use Cisco Anyconnect. My knowledge on how to set up VPNs especially in iOS verion 8.4 is limited so I've been using a combination of command line and ASDM.
I'm finally able to connect from a remote location but once I connect, nothing else works. From what I've read, you can use IPsec for client-to-lan connections. I've been using a preshared key for this. Documentation is limited on what should happen after you connect? Shouldn't I be able to access computers that are local to the vpn connection? I'm trying to set this up from work. If I VPN from home, shouldn't I be able to access all resources at work? I think because I've used the command line as well as ASDM I've confused some of the configuration. Plus I think some of the default policies are confusing me too. So I probably need a lot of help. Below is my current configuration with IP address altered and stuff that is completely non-related to vpns removed.
NOTE: We are still testing this ASA and it isn't in production.
Any help you can give me is much appreciated.

VPN between ASA5505 Easy VPN Server and 881G Router as Easy VPN Client
Hello,
I have problem in VPN between ASA5505 Easy VPN Server and 881G Router as Easy VPN Client. ASA 5505 have 7.2.3 software and 881G router have 15.1 software.
881G is configured as hardware client in network exstention mode, and it is placed behind NAT. ASA5505 is working as server. Same VPN Group works correctly from VPN software clients.
When I send traffic from 881G client side, in show cryto sessin detail I see encrypted packets. But with same command I dont see decrypted packet on ASA5505 side. On both devices Phase 1 and Phase 2 are UP.
VPN is working when I replace ASA5505 with ASA5510 correctly with have 8.4.6 software. But problem is that i need to do this VPN between ASA5505 and 881G.
Can you help me, how can I debug or troubleshoot this problem ?
I am unable to update software on ASA5505 side.Hello,

Cisco ASA 5505 Ipsec VPN and random connection dropping issues.
Hello,
We are currently having issues with a ASA 5505 Ipsec VPN. It was configured about 7-8 months ago and has been running very well..up until the last few weeks. For some reason, the VPN tends to randomly disconnect any user clients connected a lot. Furthermore, sometimes it actually connects; however does not put us on the local network for some reason and unable to browse file server. We have tried rebooting the ASA a few times and our ISP Time Warner informed us there are no signs of packet loss but still unable to pinpoint the problem. Sometimes users close out of VPN client completely, reopen several times and then it works. However it's never really consistent enough and hasn't been the last few weeks. No configuration changes have been made to ASA at all. Furthermore, the Cisco Ipsec VPN client version is: 5.0.70
Directly below is our current running config (modded for public). Any help or ideas would be greatly appreciated. Otherwise, if everything looks good...then I will defer back to our ISP Time Warner:

Thanks againHello Belnet,
What do the logs show from the ASA.
Can you post them ??
Any other question..Sure..Just remember to rate all of the community answers.

Remote site redundancy IPSEC VPN between 2911 and ASA
We already have IPSEC VPN connectivity established between sites but would like to introduce some resilience/redundancy at a remote site.
Site A has an ASA with one internet circuit.
Site B has a Cisco 2911 with one internet circuit and we have established site-to-site IPSEC VPN connectivity between the 2911 and the ASA.
Prior to getting the new internet circuit, Site B had a Cisco 877 with an ADSL line which are still available but aren’t currently in use.
The internet circuit at Site B has dropped a few times recently so we would like to make use of the ADSL circuit (and potentially the 877 router too) as a backup.
What is the best way of achieving this?
We thought about running HSRP between the 877 and 2911 routers at Site B and, in the event of a failure of the router or internet circuit, traffic would failover to the 877 and ADSL.
However, how would Site A detect the failure? Can we simply rely on Dead Peer Detection and list the public IP address of the internet circuit at Site B first with the public IP address used on the ADSL line second in the list on the ASA? What would happen in a failover scenario and, just as important, when service was restored – I’m not sure DPD would handle that aspect correctly?
I’ve read briefly elsewhere that GRE might be best to use in this scenario – but I can’t use GRE on the ASA. I have an L3 switch behind the ASA which I may be able to make use of? But I don’t want to disrupt the existing IPSEC VPN connectivity already established between the ASA and the 2911. Can I keep IPSEC between the ASA and 2911 but then run GRE between the L3 switch and the 2911? If so, how would this best be achieved? And how could I also introduce the 877 and ADSL line into things to achieve the neccessary redundancy?
Any help/advice would be appreciated!Hello,
I don't think GRE tunnel that you could set up on the switch behind ASA would be really helpfull. Still site-2-site tunnel you want to establish between ASA and some routers, but still it is ASA which needs to make decision about which peer to connect to.
Possible solution would be to do HSRP between both routers on LAN side and with two independent tunnels/crypto maps (one on each of them). On ASA you would need to set up two hosts in set peer. Problem of this solution is that if one router at side B is going to go down and second ADSL line will take over ASA will not do preempt after you main Internet connection is up again. This would happen after ADSL Internet connection will be down.
Solution to that would be to assign two different public IP addressess on two different interfaces of ASA. Then you attach two crypto maps to both interfaces and by using sla monitor (let's say icmp to main router, if it does not respond then you change routing for remote LAN to second interface) you are selecting which crypto map (with one peer this time) should be used.
I hope what I wrote makes some sense. -
Port Forwarding for L2TP/IPSec VPN Behind Verizon Actiontec MI424WR-GEN2 Rev. E v20.21.0.2
I've got a NAS setup with various services running on custom ports to help minimize exposure (especially to script kiddies). I've tested everything both internally and externally to confirm they all work, and even had someone at a remote location confirm accessibility as well. Port forward configurations performed on the Actiontec are working well.
I installed an L2TP/IPSec VPN server, tested internally and it connected successfully. So for all intents & purposes, this validates that the VPN server is correctly configured to accept inbound connections and functioning correctly.
I logged into the Verizon Actiontec MI424WR router, setup port forwarding for UDP ports 500, 1701 & 4500.
Note: I added the AH & ESP protocols based on what I saw on the built-in L2TP/IPSec rules
With the port forwarding in place, I tested VPN externally but it didn't connect.
I've done the following so far to no avail:
Double & triple checked the port forwards, deleted & recreated the rules a few times to be sure
There are no other pre-existing L2RP/IPSec port forward rules or otherwise conflicting port forward rules (e.g.: another rule for ports 500, 1701 or 4500)
There was an L2TP port triggering rule enabled, that I toggled on and off with no change
Verified the firewall on VPN server had an exclusion for L2TP, or that the firewall is off. (Firewall is off to reduce a layer of complexity, but it worked internally to begin with so I doubt that's the issue.)
Since it works internally, and there are no entries in the logs on the device indicating inbound connections, I'm convinced its an issue with the Verizon Actiontec router. But unfortunately, I'm not sure what else to try or where else to look to troubleshoot this. For instance, is there a log on the router that I can view in real time (e.g.: tail) that would show me whether or not the inbound connection attempt is reaching the device, and whether or not the device allowed or blocked it?
My router details:
Verizon Actiontec
MI424WR-GEN2
Revision E
Firmware 20.21.0.2
Verizon Actiontec built-in L2TP/IPSec rule templates. They're not currently in use, but are baked into the firmware for easy configuration/selection from a drop down menu.
Solved!
Go to Solution.normally a vpn on that router, will have a GRE tunneling protocol as well.
two ways to build the PF rules,
Manually
Preconfigured
I know the preconfigured VPN rules will do the GRE protocol as well, but if you do it by hand you can't get it. -
Need help in configuring Client to Site IPSec VPN with Hairpinning on Cisco ASA5510 8.2(1)
Need urgent help in configuring Client to Site IPSec VPN with Hairpinning on Cisco ASA5510 - 8.2(1).
The following is the Layout:
There are two Leased Lines for Internet access - 1.1.1.1 & 2.2.2.2, the latter being the Standard Default route, the former one is for backup.
I have been able to configure Client to Site IPSec VPN
1) With access from Outside to only the Internal Network (172.16.0.0/24) behind the asa
2) With Split tunnel with simultaneous assess to internal LAN and Outside Internet.
But I have not been able to make tradiotional Hairpinng model work in this scenario.
I followed every possible sugestions made in this regard in many Discussion Topics but still no luck. Can someone please help me out here???
Following is the Running-Conf with Normal Client to Site IPSec VPN configured with No internat Access:
LIMITATION: Can't Boot into any other ios image for some unavoidable reason, must use 8.2(1)

Neither Adding dynamic NAT for 192.168.150.0/24 on outside interface works, nor does the sysopt connection permit-vpn works
Please tell what needs to be done here, to hairpin all the traffic to internet comming from VPN Clients.
That is I need clients conected via VPN tunnel, when connected to internet, should have their IP's NAT'ted against the internet2-outside interface address 2.2.2.2, as it happens for the Campus Clients (172.16.0.0/16)
I'm not much conversant with everything involved in here, therefore please be elaborative in your replies. Please let me know if you need any more information regarding this setup to answer my query.
Thanks & Regards
maxsHi Jouni,
Thanks again for your help, got it working. Actually the problem was ASA needed some time after configuring to work properly ( ?????? ). I configured and tested several times within a short period, during the day and was not working initially, GUI packet tracer was showing some problems (IPSEC Spoof detected) and also there was this left out dns. Its working fine now.
But my problem is not solved fully here.
Does hairpinning model allow access to the campus LAN behind ASA also?. Coz the setup is working now as i needed, and I can access Internet with the NAT'ed ip address (outside-interface). So far so good. But now I cannot access the Campus LAN behind the asa.
Here the packet tracer output for the traffic:

The problem here as you can see is the Rule for dynamic nat that I added to make hairpin work at first place
dynamic nat
asa(config)#nat (internet2-outside) 1 192.168.150.0 255.255.255.0
Is it possible to access both
1)LAN behind ASA
2)INTERNET via HAIRPINNING
simultaneously via a single tunnel-group?
If it can be done, how do I do it. What changes do I need to make here to get simultaneous access to my LAN also?
Thanks & Regards
Abhijit
