David, This method should work, but has the disadvantage of putting all SIP behind NAT...
Assuming an internal LAN network: 10.10.10.1/24 1) in sip.conf set bindaddr=10.10.10.1 2) In the Firewall tab define NAT EXT->LAN for the 5060, etc ports to 10.10.10.1 port 5060 3) in sip.conf define both externip and localnet, something like: externip=1.2.3.4 ; the EXT interface IP address localnet=10.0.0.0/255.0.0.0 Clearly, having asterisk listen on a public IP address is the preferred method, but if you must listen on multiple ports, this should work. Note: With this solution, it is important for asterisk to only listen on the NAT'ed LAN interface, if it were bindaddr=0.0.0.0 the SIP requests would arrive on the NAT'ed LAN interface but would leave un- NAT'ed through the default EXT interface... can we say one-way audio :-) Lonnie On Sep 6, 2009, at 8:13 PM, David Kerr wrote: > I'm wondering if there are any experts out there that can help me. > Asterisk is listening on port 5060 for SIP messages.
