I have set my router to forward the port for Mumble to my server machine on the LAN. Port forwarding set up on the router ZTE MF920/MR150-5

External site (and Mumble users trying to connect to my client) report failure: enter image description here

I can connect to the Mumble server on the LAN without issue. I have restarted the router. Have I set up the mapping incorrectly, or is there an issue with the Mumble server on 16.04?

Edit: I suspect my ISP may be blocking the port, since it's a SIM based network.

  • Could you give the output form ufw status? – Marton Nov 17 '16 at 22:00
  • It says, "Status: inactive" – TenLeftFingers Nov 17 '16 at 22:01
  • Hm, that means that you firewall is inactive. But I personally tested a port I just opened and it also shows that there is no service. – Marton Nov 17 '16 at 22:13
  • In my case it didnt work because I didnt have the server running. But when I started the server it said success. Maybe thats thats what causes you problem too? – Marton Nov 17 '16 at 22:17
  • I can connect on the LAN without issue, so it is running. Thanks @Marton – TenLeftFingers Nov 17 '16 at 22:19

run netstat -an | grep 64738 to make sure the service is listening on and NOT on 127.x.x.x

  • I get: tcp6 0 0 :::64738 :::* LISTEN udp6 0 0 :::64738 :::* I'm starting to suspect my ISP is the issue and that the router is configured correctly. – TenLeftFingers Nov 19 '16 at 21:43
  • Does your router get a public IP? – meccooll Nov 21 '16 at 5:29
  • Yes, I have a public facing IP. That's how I was able to run the test with canyouseeme.org – TenLeftFingers Nov 21 '16 at 11:30
