This is what keeps my (CVS-HEAD) server happy..
bindaddr = 192.168.0.200 ; Local interface
externip = 80.63.xxx.xxx ; Public IP address
localnet = 192.168.0.0/255.255.255.0 ; Local LAN, internal clients etc.
(localnet can be repeated for each local LAN segment)
Server is firewalled and UDP 5060 and 10000-20000 is forwarded to internal
address.
External SIP clients have nat=yes, I dont see any difference with local clients
if they have nat=yes or nat=no.
