I posted this original thread, but after working on it further, I realize it is most likely a networking issue.

I have installed torrentflux on my Ubuntu 10.10 box and it downloads fine, but does not seed. I have tried forwarding ports, disabling firewalls, setting DMZ, nothing works. I can seed from other computers on the same network.

I then installed rtorrent and have tried to seed using it. With rtorrent, I get the error "Cannot connect to UDP tracker". However, I cannot seem to get rtorrent downloading either, so that could be a separate problem. Not sure what else to try, but please post any suggestions.
