Basically, the internal/external using the default UDP5060 is no problem. If I use single server, I can still connect it from outside world with port 15060. However, when I set up another (2nd) Asterisk server in the same lan, I cannot use other ports like 25060 to re-direct to the internal 5060 on the second server. That's my existing situation.
Anyway, Draytek Vigor 2930n is a good router for me, so far. Maybe, I have to spend some time to get familiar with it further. |
