Static, Dynamic & NO-NAT combination

Unanswered Question
Aug 31st, 2007

I am working on integrating two company networks. An interim soln, due to ip address collision, would require doing

Static NAT, Dynamic NAT & NO-NAT. Network A to Server Farm - Static NAT

Network B to Server Farm - Dynamic

Network C to Server Farm - NO-NAT.

Is there a sample configuration, that anyone on this forum can provide. The reason for doing Static NAT is because Network A mentioned above has other connections that conflict with Server Farm Address. So Network A will be accessing Server Farm using NATTed addresses. Users in Network B should be PATTed to another address space before they access Server Farm. Network C does not collide, in addition, it needs to be passed on as is to the parent network through Server Farm.

- Thanks

I have this problem too.

This is doable but could you just confirm what the difference between Net A and Net B in terms of NAT are.

Net A static - does this mean you want to have individual static NAT entries for each member of net A.

Net B - you say Patted to another address space. Do you mean address space or just one new IP address ?

Glad to help out with config but for your ref attached is a link to a white paper on NAT and near the end are configuration examples with route-maps which is what you need to be using.
