requests through tunnel to firewall to LAN and viceversa

[tnet2003]

Hi ,

I have a tunnel between router A and router B (827 both). Now I implemented a zywall between router B and LAN B. I also removed nat from router, Zywall use nat instead. Zywall forwards requests to router B .. then how can I forward them through tunnel? and requests from router A through tunnel how can I forward them to zywall? the problem is that requests comes from a natted ip which is the nat interface of zywall

In your new config, what are the tunnel end points? Router A - Router B or Router A - Zywall?

If Zywall is the end point, the tunneling request comes from its public interface, from Router A's perspective. You don't nat the public interface address. Wwhat you nat is LAN B.

Hope this helps

Have a look at this discussion about running IPSec through a NAT Firewall :
