I posted this in the Network forum, but I thought I might get better help here. I have a BEFSR41 V2 router using the lastest firmware (1.46.02) connected to an ADSL modem. My bittorent client (Azureus) shows a NAT error. I've tried - Using the "Port Forwarding" menu to forward the appropriate ports - Using "DMZ" (set to my IP) - Setting a static IP address in WinXP with the following info: IP: 192.168.1.72 (Making sure DHCP range does not include this IP) Subnet Mask: 255.255.255.0 Default Gateway: 192.168.1.1 Preffered DNS: 192.168.1.1 - Disabled all software firewalls completely - "Shield Up" shows my ports as "Stealth" - Tried plugging modem directly into ethercard card, bittorent works fine - Unplugged all other computers from router just in case - I've also reset/re-installed the modem, router, ethernet card. I've even reinstalled Windows I'm thinking the problem is with my static IP in Windows, but that's just a guess. The only part of the Static IP setup in WinXp I'm not sure of is the "DNS server" part. Some tutorials said I must get it from my ISP, some said to just enter my router's IP. I've been using the router's Ip, and I can connect to the internet fine. Can this have ANY effect on port forwarding/DMZ? This is driving me nuts, as I've spent at least 10-15 hours scouring forums and tutorials, but nothing works!! Any help would be GREATLY appreciated.
