I have several people now interested in doing 1-1 address translation at a
router, including some large sites. Can Linux do this now? I have heard
some Cisco routers do it.
Network Address Translation differs from masquerading and proxying in that
each host has a unique IP address on the "outside" network, but may be
using a different address inside. It would be sufficient to translate any
addresses in a large block to a different block of addresses in a 1-1
manner, though for migration purposes there may be a mix of addresses in
the "inside" and "outside" blocks on a temporary basis.
This sounds easy in general but may fail for things like talk which embed
IP addresses inside the data.
