NAT and IPSEC Tunnel

[deebee122]

Hi guys,

I have set up an IPSEC tunnel to a remote site on my Cisco 1841 router. The tunnel is up and running but i need to do some NAT'ing on my side and im having some problems regarding that.

here's the set up:

Source<--->router A<---->router B<---->destination

Source IP: 196.10.10.57
Destination IP: 150.10.10.1
NAT IP: 150.20.20.1

Basically what needs to happen is that when traffic from the Source IP(196.10.10.57) attempts to connect to the destination IP(150.10.10.1) the source IP should be NAT'ed as 150.20.20.1.

I've tried a couple of things from howtos and guides and has so far been unsuccesfull, any help would be greatly appreciated.

Thanks!

your source and destination IP's are routable internet IP's. make them private and your nat will be smoother. also, post a config of router A and B
