Hi,

I am trying to port forward for torrent and also for Xbox LIVE. I know how to port forward, have done it many times but I am having real problems getting my xbox to connect to LIVE and if it does it is always a strict NAT.

My router is a Belkin F5D8636-4 and I just updated to the most recent firmware as I thought it would help. I saw in another forum to check the ports with PFPortChecker so I have forwarded the ports I need for LIVE and the torrent program to my computers static IP of 192.168.1.2 and the TCP of all the ports are open but all the UDP are closed...

I have tried having the settings say TCP&UDP and also separating them out individually but no luck. I can't find anything much on the net about it.

Would this be a router problem? Or could it be ISP blocking UDP (I'm with Orcon)?

Any help would be appreciated.

Thanks

Ragnor

Sounds like you need to forward the ports for LIVE to the Xbox's IP Address not your computer/PC's IP address to me.

I realise that but this program cant tell me if the port is forwarded to my Xbox's IP so I tested it with my computers. Anyhow I figured out that the reason is my firewall was blocking the UDP for some reason but it wouldnt be doing that on my Xbox.

However it does seem to be working with occasional disconnections with the DMZ.

Another option is to enable UPNP in the advanced user interface in the router admin. Then you don't need to bother with any port forwarding. UPNP allows applications on your devices to tell the router what ports they need temporarily need forwarded to where automatically.

It's a small security trade-off for a big conveinience gain imo.

The pro is no more manual port forwarding for applications that can use UPNP eg Xbox Live and uTorrent

The con is if someone using your internet has a compromised machine then the malware on their machine could request via UPNP ports forwarded to that machine which means that machine could operate as a server for spam etc.

If all your machines are running Vista and decent AV and you don't have any noobs installing random junk then I'd go with UPNP on.

Thanks for the replies. Unfortunately I have tried the UPNP option and it doesnt seem to work at all. Strict NAT all the time. I seem to have fixed the issue though, although I get some disconnections I cant quite work out.

All I did was disable UPNP, remove any port forwarding I had for the xbox, and enable the xbox's IP in the DMZ. Seems to result in an open NAT. As for the disconnections... I dont know, I seem to get them quite frequently when browsing on my computer too so maybe its just the router.

Thanks for the help.
