[Asterisk-Users] Problems connecting to and from my Asterisk server :(

[Moises Silva]

i cannot give you guarantee, but this is a shorewall rules file (
popular firewall )  that can give you a clue about what ports need to
be open for Asterisk

The issue with the SIP phones may depend on your LAN configuration. In
fact, NAT can be the problem. SIP does not work very well out of the
box behind NAT, please make a search in google about "sip asterisk
nat" to find out some solutions.
