I need machines on the LAN to be able to access by the external address or hostname. If it can't be done, then just by hostname is OK as well, so I thought of just doing it through DNS on our internal DNS server (a Linux machine), but I don't know how to make that have different ports go to different LAN IPs.
I don't have much experience setting up routers. I just purchased a western digital mytouch1300 and its pretty apparent the company didn't do their homework before releasing it. Well. I called their support line and they tried to get the setup cd running for me but they gave up. They also tried going through the address bar and that didn't do any good either.
