Re: [FW1] pop3 gateway



OWA works pretty good., but do yourself a favor and don't allow the remote users
to change their passwords via OWA because you have to use the IIS ADMIN pages
which are pretty exploitable.

If your users ALREADY must select the right POP3 server for the account they
are using, what is the problem with taking those 5 exchange boxes and statically
NAT'ing them each to it's own public address and just allowing POP3?

If you don't have enough addresses to do that, you can do PAT.
Just allocate some different ports to use for each POP3 server and use the nat
translation tab to nat them inbound and slap the proper destination address and pop3 on.
