Site-to-Site VPN Using Router and ASA

Answered Question

Hi,


I have a Cisco 1812 router which is setup for remote access VPN using IPSec (Cisco VPN Client), my question is can I configure a Cisco ASA 5505 to connect to the router as a site-to-site VPN.


Thanks


Karl

Dear Karl,


Yor are right, in this case either you can created a site to site vpn tunnel between the devices or you can setup your ASA as a VPN hardware client. ie; Easy VPN.


For the same you can refer the below document.

Hi Shijo,


Thanks for document very helpful, one last question?


Since I already have the router setup for remote access for end users to VPN into the local LAN can I use the existing setup on the router, an just configure the ASA to connect to the router.


I know on routers you can setup an Easy VPN Remote which connects to an Easy VPN Server which is what I have setup, so the ASA should be able to do the same would you agree?


Many Thanks


Karl

As mentioned by Shijo, it is no problem to do that. Just make sure that the crypto-map-sequence that you use to apply your dynamic crypto-map is always higher then the sequences you use for site-to-site. That's a config-mistake I have seen more then once.
