Site to Site VPN between sites with similar subnets

[ribin.jones]

Hi,

I have two sites A and B. I need to do site to site VPN between these two sites. My problem is that, both the sites have the same range of internal IP's (192.168.100.0/24). How can I get the vpn configured in this situation?

Thanks for any help.

Hi,

if you set up source NAT'ing on one side, this should work pretty well.

Hi,

Thanks for the reply.

I have ASA at Site A and Cisco 2811 router at Site B. If I choose to do source NAT ing at Site B (Cisco router), can you tell me the steps/configs that I need to do for this?

this one should work fine :

(of course you need to use a default route on the router to send traffic across)
