Port Forwarding

[scott2020]

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...
