How to setup that kind of VPN IPSEC?

Unanswered Question
Jul 14th, 2008

Hi,

I have a 1841 router with Ifirewall IOS behind a public IP.

On the remote side I have a 1801 which is behind a modem/router.... therefore it has a private adress on its outside interface.

Central Router (Pub IP)---- Internet ---- (Pub IP)Modem/router ---- (Private IP)Router

Is it possible to setup an IPSEC VPN ? I try a lot of thing but nothing work....

Does anyone has a solution with a working configuration?

Rgards

I have this problem too.

you need to have a static NAT translation on the Central Router for Private IP of your 1841 router

I'm not sure I understand your answer....

But something else... The 1801 router is behind a router/modem that get a dynamic IP...
