So I'm trying to run Murmur (the server for Mumble) on OpenWRT but for some reason I'm unable to open the port for it. I've installed the umurmur-polarssl package and followed the howto on configuring it (although I changed the default port), and I've tried configuring the firewall to open the port through LuCI and by editing /etc/config/firewall as noted here, but whenever I try to connect to it I get "connection refused" (both trying myself and by using http://www.canyouseeme.org/). Any suggestions would be greatly appreciated.

EDIT: I was fooling around with it last night, apparently I can't open any ports except port 80, which leads me to believe that my ISP may be fooling around. However, all my port forwarding works fine, so I don't think the ISP is blocking any ports, but I'm not sure.

Can you show your "iptables -L" and "netstat --inet -lnp"?

Sorry for wasting your time. Not quite sure what I was doing Monday night, but I went through all the web pages setting it up from scratch and it worked last night.
