Router-to-router VPN tunnel

This is my first time setting up an IPSEC tunnel between two routers. Can someone recommend a document that can help me configure a tunnel for two routers to be connected to each other through the Internet?

These documents will be useful to you. These documents explain how to setup IPSEC tunnels using two routers.

Router-to-PIX VPN Tunnels fade in and out

Does anyone know of any problems with Router-to-PIX vpn tunnels? For a number of months we've had about 35 831Routers vpn'd into our PIX515 and the tunnel has been stable. Recently, however, the tunnel has been dropping out at a number of sites.
When the tunnel goes down the users still have access to their local internet but obviously not to the shared network resources of the vpn tunnel. In most cases the tunnel can be re-established at each location simply by rebooting the router. Only problem with that is that some of the locations are having to reboot their 831Router more than two or three times a day.
I've added keepalive statements into theconfig of the routers and the PIX. Specifically I've added these two lines to the routers:
Crypto isakmp keepalive 10 5
crypto ipsec secutity-association lifetime seconds 28800
I added a similar isakmp keepalive to the PIX. Any suggestions would be appreciated as some of my users are getting frustrated.
Thank you,
Chris

Try using the debug commands and see if you are getting any error messages that might give us some idea.

EZVPN Router to PIX - vpn tunnel fails after xauth

I'm trying to configure a 1721 router to connect to a PIX at the office, essentially putting the router in place of a software VPN client. I can connect to the PIX with both a software VPN client and a hardware VPN 3002, but whenever I try to configure the router with EZVPN, the tunnel fails to come up after the XAUTH negotiation. I've tried a few variations on configurations with no luck. Can anyone comment if this is possible? I've attached a config and debug info. Thanks in advance for any help and comments.
Ken

Thank you for the suggestions. Currently, the PIX is configured to not allow the save password option on the remote end. Was hoping the PIX config wouldn't need any changes since its working for the software VPN clients. I tried your NAT suggestion:
ip nat inside source list 100 interface Ethernet0 overload
ip nat inside source list Lan_Addresses interface Ethernet0 overload
ip access-list standard Lan_Addresses
permit 192.168.5.0 0.0.0.255
access-list 100 deny ip 192.168.5.0 0.0.0.255 10.0.0.0 0.0.15.255
access-list 100 permit ip 192.168.5.0 0.0.0.255 any
This didn't change things. Also, things behave differently when I use a bad username/password, for example:

Which wireless router do I need for multiple VPN tunnels?

I work at home and I connect to my office VPN (SSH Extranet Client) thru cable broadband. I need to have 2 VPN tunnels open as I frequently have my laptop & desktop connected to my work VPN. I've had a BEFSX41 for the past 3 years and it's worked good as it allowed for 2 VPN tunnels. It just died on me a few days ago and I would like to go wireless now. What wireless router(s) would meet my needs? Thanks in advance for any input.Message Edited by nolesworld on 11-27-200606:24 PM

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.

Router to Router Dialer VPN

one of my router is configured with site to site vpn, I want this router to establish a dialer vpn from a remote router,
Remote router will be configured as dialer vpn as there is no Live IP available in remote site, I dont want to configure it as Site to site vpn,
Please refer some docuement to achive this goal,

Hi Karsten -
I'm afraid I cannot use the EasyVPN feature at all.
The vendor informs me that there is another IPSec VPN tunnel which connects back to their office to provide other capabilities.
So I have to use L2L IPSec -- and do it with a dynamic IP from the router side, to a fixed IP on the ASA side.
Is it possible to build the tunnel-group on the ASA side so that it doesn't require a known IP for the remote side of the tunnel?
I'm using DefaultL2L tunnel group (on the ASA) at the moment to terminate the VPN when the router is using the satellite connection via FA90/1, with a fixed IP address.
But the DefaultL2L group doesn't have the IP of the router -- yet it works...
The same VPN config, used from the FA0/0 interface of the router with the same crypto map
just gives the traditional "No match, deleting SA" message..
I can see the router trying to establish the VPN, but it's just not able to negotiate, and the only reason I could think of was that the FA0/0 interface had a DHCP address instead of a static IP.
Strange that it works OK with the ASA's DefaultL2L tunnel group, with no mention of the router's FA0/1 static IP, yet the FA0/0 with a dynamic IP won't work.
We did just hook up the satellite and used FA0/1 to test it -- vpn came up instantly...

VPN Router to Router with 192.168.1.1 WAN address

I have two WRVS4400N routers I'd like to create a VPN tunnel for.
One gets a WAN IPAddress totally external: 75.32.167.xxx from the DSL modem.
The other one is connected to an ADRAN 676 modem.
This modem has an external IP address (67.155.29.202), but assigns address 192.168.1.1 to the connection to the router.
I have the router configured to assign addresses 192.168.0.xxx to all computers on the LAN.
The VPN setup requires to define the WAN address as the external address, but my router only sees address 192.168.1.1 as the external address (coming from the ADRAN modem)
I hope this is not too convoluted and someone can help me. Following is an attempt at illustrating my setup:
10.10.10.1-->Router1--->75.32.167.147 ---->INTERNET--->
INTERNET-->67.155.29.202--->ADRAN modem--->192.168.1.1-->ROUTER2--->192.168.0.1
Thanks in advance
Rodolfo

You adran modem also operates as NAT router. You have to reconfigure the adran modem for bridge mode. In bridge mode the modem operates like any other simple modem. You then have to configure the router for your internet connection, e.g. use PPPoE with the username and password supplied by your ISP. With that your router will have the public IP address.
Otherwise, you would have to configure port forwarding and IPSec or GRE forwarding on the adran to pass the VPN traffic to the router. However, this may not work at all if the router is not able to handle VPN traffic through your NAT adran modem/router (my guess is it won't do it but I have not tested this).

Router to Router VPN with Overlapping internal networks

Hello Experts,
One quick question. How do I configure a Router to Router VPN with overlapping internal networks???
Both of my internal networks have ip address of 192.168.10.0 and 192.168.10.0
Any link or config will be appreciated. I've been looking but no luck.
Thanks,

Router-to-Router VPN Security

Hi there,
Should we worry about the the security on router-to-router VPN over internet (IPSec) ?
We have two offices.
Office A has Cisco 2811 router (internal, private) and ASA 5510 firewall.
Office B has Cisco 2821 router (internal, private) and ASA 5505 firewall.
Office B has private subnets that extend to 7 hops away. (running RIP)
If we want to set up a site-to-stie VPN between these two offices, should we set it up on ASA's or routers?
If we set up VPN on routers, does that mean we need to connect one interface to the internet on each router and suffer from Internet attacks?
How do we defend our routers then?
Thanks in advance!
-Andrew

Hi,
when it comes to site to site vpn I usually prefer routers. Whith a little bit of tweaking NAT and routing you should be able to operate a public address on the routers even if they are behind the firewall.
The advantage of IOS based VPN is e.g. the possibility of routing protocols through the VPN tunnels which would give another level of resiliency. Configure tunnel interfaces on the routers with a tunnel mode IPsec and a tunnel protection profile. You can then run e.g. EIGRP to find a possible alternate path if one of the tunnels fails. Its much easier than anything I can think of on the ASA.

Setup router to router VPN connecting 2 windows domain networks via 2 RV042 routers

I am using 2 RV042 routers. I have created a point to point VPN with Remote Security Group Type= Subnet, using the default IPSec settings.
Under advanced settings- Aggressive Mode, Keep Alive enabled.
Location A- SBS 2011 standard, Servername=SBSServer, Domainname = Smallbusiness.Local, IP address 10.1.10.50
DHCP range 10.1.10.100 to 10.1.10.175. DNS and Print services. No WINS.
Location B- Server 2008 R2, Sername=SBSServer, Domain name=Smallbusiness.Local, IP address 192.168.10.50
DHCP range 192.168.10.100 to 192.168.10.175, DNS, Print Services and Remote Desktop Services. No WINS
I am wondering 2 things. Can I setup the VPN tunnel to route traffice between the 2 networks without changing the server names. Leaving the servernames the same. I have it setup that way but also had netbios broadcast enable. If I disable netbios broadcast will that be enough for these networks to be independent of each other. I was hoping not to have to rename the domain and there are advantages to having the same user and domain name when mapping drives between networks. I have not needed to authenticate those drives or provide credititals for printing either.
2) Should I change the domain name so that each network has a unique domain name or, if I change the servername of the 2008 R2 server will that essentially solve my network issues, the primary issue being that location b has clients that occasionally can not find the 2008 R2 domain controller. After a restart the usually resolve to the correct domain controller.
Essentially what I am asking is what are the best practices to connect 2 separate Windows domain networks via a VPN and have those networks capable of file sharing to the each others domain server and printing to the network printers at both loations.
Should I have separate domain names-
Should I have separate server and computer names-

"reserved not zero on payload" generally means your pre-shared keys don't match. Try removing the "crypto isakmp key ...." line and retyping it in again on both sides. In particular DON'T cut/paste it from one router config into another, this quite often puts a space character onto the end of the key, which the router interprets as part of the key and they therefore don't match.

well, the client can connect to VPN router and i can verify the status online on tab vpn BUT
after 2-3 min. client receive the error message
"the gateway not responding"
AND
if client tries to ping from command prompt to the local ip addresses he find "negociating IP security"
status of router is :
- all security including firewall is disabled
- i have public IP address on Router having 255.255.255.0 subnet
- my local subnet is 10.10.1.x
please tell me what should be done
Thanks
Message Edited by SHAQ on 12-18-2007 09:26 AM

try upgrading / reflashing the firmware of the wrv54g to the latest available from www.linksys.com/download
try changing the MTU size on the client router to 1452
check whether it makes any difference

SAP router installation for VPN method

Hi All,
Can any one share me the steps to perform SAP Router Configuration with VPN method.
Also what are changes i need to make in saproutab file.
Appreciate your inputs.
Thanks
Pradeep.

There is paperwork that you need to fill out with IPSec information, once its filled out you fax it over to SAP.
Not entirely sure what changes need to be made in saprouttab? Are you changing SAPRouter to no longer perform SNC to SAP?
Here is the doco I used for my company - https://support.sap.com/content/dam/library/SAP%20Support%20Portal/remote-support/RemoteSupport.pdf

Cisco 831 Router to Configure VPN Access

Hello,
I need assistance in configuring a VPN in a Cisco 831 Router. I do not have any experience in configuring routers and VPN's, and would appreciate if any one could help out.
I would like to connect three Laptops to the Cisco 831 via Cisco VPN Client. Three laptops must have 10.42.6.x Address assigned by the router on the VPN Connection. They will also need access to the internal network which is 192.168.x.x private network. The Cisco has a Static IP on the Internal Interface and External Interface. I have tried several different ways of doing this, however I must be doing something wrong in my config.
Any help or suggestions would be appreciated.

Hi Robert
You can refer the below link in finding out the exact config to start with.
do make sure that your Cisco 831 box with the current IOS code installed in it supports the required feature to run the same..

Configure a VPN client and Site to Site VPN tunnel

Hi, I'm setting up a test network between 2 sites. SiteA has a 515E PIX and SiteB has a 501 PIX. Both sites have been setup with a site to site VPN tunnel, see SiteA config below. I also require that remote clients using Cisco VPN client 3.6 be able to connect into SiteA, be authenticated, get DHCP info and connect to hosts inside the network. However, when I add these config lines, see below, to SiteA PIX it stops the vpn tunnel to SiteB. However, the client can conect and do as needed so that part of my config is correct but I cannot see why the site to site vpn tunnel is then no longer.

Hi Rizwan,
Thanks for your response. I updated the configuration per your response below... It still doesn't work. please see my new config files below. Please help. Thanks in advance for your help....
Hi Pinesh,
Please make follow changes on host: officeasa
remove this line below highlighted.
crypto dynamic-map L2LMap 1 match address Crypto_L2L
It is only because group1 is weak, so please change it to group2
crypto dynamic-map L2LMap 1 set pfs group1
route outside 10.10.6.0 255.255.255.0 96.xxx.xxx.117
Please make follow changes on host: homeasa
It is only because group1 is weak, so please change it to group2
crypto map L2Lmap 1 set pfs group1
route outside 10.10.5.0 255.255.255.0 xxx.xxx.xxx.xxx default gateway on homeasa.
Hope that helps, if not please open a new thread.
Thanks
