Hi,

IPSec tunnel is running between 2 sites.Now we need to configure static NAT for 1 IP address comes under overlapping subnet.

When we configure static nat then whole traffic is transfered to the static nat connection and my tunnel see not traffic.

Any idea how to solve this problem.We need:

1. IPSec tunnel should work under overlapping n/w

2. static will also work


We could not able to do any config changes at the other site os the tunnel .

Hi Vikas

you can use policy nat like following

lets say that if x.x.x.x in inside wants to reach y.y.y.y, it will be translated(static nat) to z.z.z.z on outside interface


access-list policy-nat permit ip x.x.x.x 255.255.255.255 y.y.y.y 255.255.255.255

static (inside,outside) z.z.z.z access-list policy-nat
