Port Forwarding

[chpalmer]

It would be an interesting statistic, to learn about what modem combinations need port forwarding, and if more than the key port needs to be forwarded.

Good idea usa2k- Ive just started a post with mine...

I have multiple systems at the office and of coarse Voipo here. Im constantly moving and testing things and never need any port forwarding. But I believe that some manufacturers just don't have enough knowledge to properly handle voip through their devices.

My firewall does not like to allow incoming calls unless they originate from the carriers port 5060 (or whatever my device is pointing at) so I simply give the carrier server a firewall rule to allow all ports and problem solved.

I had a voice gateway I left 5060 open to pretty much every connection. That was a mistake! Basically someone could enter phonenumber@my ip address and the call would go through. Not good! I have since locked it down so don't go getting any ideas!

Your running a sip server?

My rule is setup as-

174.37.45.134 - UDP - all ports > lan address all ports (I do this for each of Voipo's servers.)

So unless sip-*.voipwelcome.com gets hacked or someone spoofs one of their addresses, ect... I should be safe...
