[asterisk-users] Asterisk not receiving call from VPN address

[David Cunningham]

Hi Paul,

Using ngrep/tcpdump shows the packet clearly going from the Kamailio server
and arriving at the Asterisk server. This is why it's a mystery that
Asterisk doesn't see the call coming in. We tried removing the firewall (so
iptables -L shows no rules at all) but that didn't help unfortunately.
