I have a network that consists of a Netgear DG834 and an Apple Airport Extreme for wireless.
I have managed to set up transmission to work on my router, but I can't seem to get it going outside of that. I am assuming my set up with the Netgear is wrong.
In the netgear I have added a TCP/UDP Service on port 9091 called Tranmission.
I have then added firewall rules with this service, setting outbound and inbound to Always Allow, and attached the Airports local IP as the LAN Server IP, and the LAN User.
I am able to log into the Netgear using its external IP, but when I try to get through port 9091 (by appending :9091 after the external IP) I get a 404.
