I might have found a problem with Thibor 10192005 release.. I had Thibor working fine and its a great firmware.. My ip was 192.168.103 and had azureus running fast and smooth with no Nat problem but then my router changed my ip to 192.168.100 and so I changed all the port forwarding to the new ip.. Thats when the problem started, my Azureus showed all my connections as NAT. The only way I got it bt working again was to use a static 192.168.103 ip even though I had port forward to the correct port when the ip was 192.168.100.. I was looking at the iptable and notice: 10 logaccept udp -- anywhere 192.168.1.103 udp dpt:1070 11 logaccept udp -- anywhere 192.168.1.103 udp dpt:1720 12 logaccept tcp -- anywhere 192.168.1.103 tcp dpt:1720 13 logaccept tcp -- anywhere 192.168.1.100 tcp dpt:1720 14 logaccept udp -- anywhere 192.168.1.100 udp dpt:1720 Can anyone explain what was happen? As you probably notice im a newbie with linux/networking Thanks!
