I solved a similar problem configuring an internal DNS server and
the web/ftp server names to the internal IP addresses.

Or do you want to be able to access your servers with the external IP
addresses and not the
given hostnames?

Perhaps an entry in /etc/hosts will work for you, depending on what kind
network you have (Unix/Linux or other not using /etc/hosts, or too many
Unix/Linux so updating /etc/hosts would be painful so beter configure a
DNS server?)

You could also filter packets coming from your local network on the
firewall with destination IP set to your external servers and change
their destination IP to the local one. (static NAT)

Have a look at the iproute2 package!
ip route add nat ... via ...

Lots of possibilities as you can see!

Bye, Richard

Unix IS user friendly. It's just selective about who its friends are.
