Hello, I'm new to this forum.

Recently I did some port forwarding to get faster downloads on my bit torrent client (Vuze). Now I can't send or receive emails on Entourage or through my Gmail account.

If I shut down the computer and re-boot router and modem, I can receive emails once, but if I try a second time, it's no go (error message -23016 in Entourage, server not responding error in Safari/Gmail). Regular internet connection comes in just fine and Vuze is working (faster, too).
I figured I did something wrong in the port-forwarding process. So I cleared the port forwarding in the router and enabled UPnP there and in Vuze as well. But still no emails unless I shut down, unplug and reboot. Why would I be able to surf the Net but not receive my emails?

Please, can anyone help?

Specifics:
Intel Mac OSX 10.4.11 using built-in ethernet
Netgear RP614v3 Router
Scientific Atlanta cable modem EPC2505

Vuze TCP/UDP port : 63128

Firewall is off
Entourage Office X

Thanks in advance!

Thinking out of the box here, but there isn't a large message trying to download from the Gmail server? Or is there a message sitting in the outbox holding up the email client's connection to Gmail?

Failing that, i would reset all changes and start again.

Other thing is to try port scans against your external connection (www.grc.com and run the sheilds up scan) post the results back here.

Cheers

Thanks Jaymz.
No, there are no large messages holding anything up. When I shut down, unplug the modem and router and reboot, I receive email (from my ISP) and Gmail with no problem. But just once. Then it bugs out again.

when you say resest all changes: what changes, where?

I'm afraid the port scanning is a little over my head. I did run two tests on ShieldsUp (common ports and all service ports). The results are below. Any ideas?
Thanks again.

What happens if you shutdown and restart, but don't start Vuze? Will gmail work correctly then?

If I simply restart the computer without unplugging the router and modem, gmail/entourage do not work, even if Vuze is not running.
If I unplug router and modem and restart, without opening Vuze, I can access mail through gmail and entourage, but only for a short time. If I surf the internet and then come back to my Google homepage, gmail won't load.

Do you happen to have a spare modem at home? My thoughts are for you to reset the modem back to factory default (after you pull the username and password from it of course).

Then start again with an unmodified modem. It definately sounds like the problem lies with your networking gear

Thanks but no, I don't have a spare modem. Why would the hardware be a problem if I'm still able to surf the Internet? It's as if everything but my POP mail and Gmail accounts are able to find open ports. Is there something I have to enable in Entourage/Gmail to get them in sync with UPnP?
