Postfix e-mail server on virtual Fedora 7

I'm having some trouble figuring out where the hangup lies on a connection issue. I have a domain with an MX record and A record pointing to a router. That router points ports 110 and 25 to an internal IP address that's attached to a Fedora mail server being run in VMware on top of Windows XP. When I try to telnet to localhost at 110, it works fine. If I try to telnet to the FQDN, it looks at the proper IP address, but then hangs. I opened ports 110 and 25 in iptables, but it still hangs. No firewall is being run on the guest os. Any ideas?

How did you set up the VMWare networking? My first guess would be that your host operating system (XP in this case) is blocking the connection request. Another good guess would be that you haven't pointed the router to the guest OS.

Most likely you will want to use Bridged Networking for your VMWare machine. Collect the IP address the router gives you, and enter that into your router's port forwarding options.
