NAT Issue

We are trying to connect 2 separate sites together. Site A is the main network and Site B is a private LAN (only local servers). For various reasons servers in site have a different GW than the router address connected between Site A and Site B.

We want the following to work:

We access a server from Site A. Server address is internally (Site B) and externally (Site A).

This will work if the server in site A ( has (router internal address) as the gateway as it normally should have.

We use this command to do the static nat translation:

ip nat inside source static extendable.

I don't know if this is possible, to NAT the source address (192.168.x.x) to a local address pool (let's say -50) and server in Site B communicate internally with this address? Can any of you help me, I would be very grateful.

Outside to inside traffic

source 192.168.x.x -> dest ->

Inside to outside traffic

source -> dest -> 192.168.x.x

Is is possible to solve this with, without exploitng network

Re: NAT Issue

Nating can be done by creating pools and associating it with access-list .you can go through a very good documentation by cisco as given below.

If you trying to do nating with overlaping you might require a DNS configured .
