I am in need to establish a site to site VPN between 2 cisco routers. One router does not have internet access. I need to make our ASA 5505 its gateway to the internet. I need to make the 2811 router visible in the internet. I have an external IP address I can give it in one of the interfaces (fa 0/0).
I am thinking of using one of the interfaces of the ASA5505 as a DMZ for the Cisco 2811. My questions are for the necessary commands to make this happen in both devices. Is this possible?
Here is an illustration attempted of what the idea looks like.
---voice and data --SA-router 2811¿----¿ ASA5505 VPN internet VPN ASA5510 ¿--¿
HOU-router---voice and data traffic
I only need this for one router by the way. I am more challenge in the asa5505 part.
We tried the site to site VPN between the firewalls but it didn’t work.
