The 3Com router has all portforwarded: TCP port 1720 TCP port range [30000-30010] UDP port range [5000-5016] UDP port range [5020-5023] Start gnommeeting Click the Configuration Druid STUN test result: Blocked. 2. Delete the below ports TCP port range [30000-30010] Save the 3Com router state. Check that the forwarded ports are the right ones. Quit gnomemeeting Start gnommeeting Click the Configuration Druid STUN test result: Blocked. 3. Additionally, delete the below ports UDP port range [5020-5023] Save the 3Com router state. Check that the forwarded ports are the right ones. Quit gnomemeeting Start gnommeeting Click the Configuration Druid STUN test result: Blocked. 4. Additionally, delete the below ports UDP port range [5000-5016] Save the 3Com router state. Check that the forwarded ports are the right ones. Quit gnomemeeting Start gnommeeting Click the Configuration Druid STUN test result: Blocked. 4.1 rm -rf .gnome2/gnomemeeting 5. Finally, delete the below ports TCP port 1720 Save the 3Com router state. Check that the forwarded ports are the right ones. Quit gnomemeeting Start gnommeeting Click the Configuration Druid STUN test result: Blocked. 6. Power off an on the 3Com. Check the forwarded ports. STUN test result: Blocked. 7. Repeat the SJPhone test. It works. 8. Quit gnomemeeting Start gnommeeting Click the Configuration Druid STUN test result: Blocked. Note: Changing to stun1.vovida.org does not help. Let me know if you need further information. Any hint is welcome.
