When you say "absolute links", do you mean URLs containing IP addresses
instead of hostnames?
If you mean "absolute links" as distinct from "relative links" (using
hostnames) then providing you have your DNS set up correctly, so that
external queries receive public addresses and internal queries get internal
addresses, there should be no problem.

I suspect that mod_rewrite may be able to do what you want; however I
recommend you also investigate a proxy server (Apache or Squid would do the
job) in what is generally accelerator mode (ie the proxy is at the server end
of the link instead of the client end), as this can listen on a public IP
address, receive queries from the Internet, and then make local requests to
the true servers on private IP addresses.
The same proxy could be used for internal and external clients if you wish.
