Remote access VPN and site-to-site VPN connections on one router
Posted on 2008-10-07
Currently have a Cisco 2610 router configured for remote VPN access via the Cisco VPN Client. We would like to also use this same router in a site-to-site VPN scenario to another office. Is it possible to provide both these services with this one router and one public IP address? I thought you could only apply one crypto map to the outside interface?
Below is our current running-config; Thanks for any help.

I do this on a Netscreen 5 GT, so I would think that it should work on a Cisco, but it may be device dependent.
I applaud your effort and participation SysExpert. Unfortunately however, that was not very useful to me.
Yes, you absolutely can setup both site-to-site VPN and remote access VPN on a Cisco router. I do it all the time.
What exactly do you need help with? I see that you've already got remote access setup. The two can be configured side by side with no problem - just make sure your router has enough throughput to handle it all.
Here is a link to setting up site to site on a 2600 router - this should get you up and running! Go to the bottom of the article and download the "template" - this will automatically generate all commands you need to get this working. You do need an account to get this but the signup is free.

Cheers! Let me know if you have any questions!

I guess the help I am seeking or where the confusion stems from, is I'm pretty sure you can only apply one crypto map per interface. So I have one applied now for Remote Access and am perhaps unsure how to modify the existing crypto map to accommodate both. Excellent link you provided though Puggle! Thanks!
You use the same crypto map. Do you have a contract on the device? If you do, just contact Cisco and they'll guide you through it. Otherwise, post your config and I'll take a look.
Cheers!
Cheers!
No Cisco contract unfortunately. The config is posted above in my original post; did you need something else that will help? Thank you for the assistance.
