As seen by the logs on smoothwall: http://www.lindsay.ath.cx/stuff/firewalllog.dat.html

Normally the only traffic that is logged are connections from the WAN that get dropped by iptables. Traffic on forwarded ports does not get logged. As you can see by the log, ktorrent is producing quite a bit of traffic that for some reason is getting logged. And the amount of traffic that it is logging will turn a small log file into a 20mb one over night which causes memory problems on smoothwall.

The computer with ktorrent on it is 10.36.36.199 and the external IP address is 72.183.201.32. Ports forwarded to 10.36.36.199 on smoothwall are 6881 tcp&udp and 4444udp.

Why ktorrent is trying to connect to the ip it is running on I don't know. It only happens with dht on. Everything is fine with it off. Also according to the logs from ktorrent, it is trying to get sources from my external ip address (72.183.201.32). Why it does that I don't know:

Perhaps ktorrent doesn't like NAT? Is this information enough for someone to trouble shoot? I can provide more if needed or run network traffic sniffers....

I really don't think this is a smoothwall problem since I have ran lots of other p2p apps before and I have never ran into a problem like this.


Thanks!

Because of the NAT, KT doesn't know the WAN IP address. With DHT you can easily get your own IP address back, which is not really a problem, if you connect to yourself, the connection will be refused.

Hmm so because of that it is getting logged I guess?

That, along with repeated attempts to contact peers that may be refusing connections.
