Ok, we have a Cisco 2610 router here @ work running IOS v12.0.

Our LAN is currently configured for a 193.x.x.x address (I know, it's historic so don't ask why). I need to re-configure the LAN to a 192.168.10.x private address.

Fair enough, this is easy with all the other equipment, but this router is a direct connection to one of our clients networks. The techie at their end said that I would need to do the translation at our end. He was very vague about what he meant, although I read this as saying he meant NAT.

We have printers here that get send jobs from a few Unix hosts over on the clients network. If I configure NAT, then this won't work unless I try to differentiate using port numbers.

Do I need to use NAT with this router if I use a private address? I mean, the software will let me configure it with or without using NAT?

You should just need to add a static NAT translation from the old address the unix servers are contacting to the new addresses the printers are using.

You could also have a look at thier addressing plan and see if introducing the 192 address would cause any problems.

Thanks.

Spoke to their Techie this morning and they aren't using that range of addresses, so I can just setup routing rather than using NAT.
