NAT and inside ip to an inside ip, possible?

Chris Tolley

We have a situation where we were to setup a tunnel from a remote site to our internal net. We were

to provide an internal subnet that the remote site used to NAT from their net to the provided subnet

from which they can then access other internal subnets.

REMOTE - 10.x <NAT> 172.10.100.x <-tunnel-> - LOCAL

The problem we have is they need to access a subnet on our internal network (lets say 172.10.90.x) that

they are using on the remorte side. Since they cannot access directly they have suggested we NAT

a portion of the 172.10.100.x subnet to the 172.10.90.x subnet (but not all of the subnet).

REMOTE - 10.x <NAT> 172.10.100.x <-tunnel-> 172.10.100.x <NAT> 172.10.90.x - LOCAL

Is this possible?

Hello Chris,

Does not know if its just me but I did not understand your question!

Can you try to do it one more time?
