Is Kamalio running on the same system as Asterisk?

Hi Larry,
Thanks for the reply. We have all of those settings left out of our
sip.conf, so this should allow everything, right?

Hi,
We have a Kamailio and Asterisk cluster, both machines being on
a real
103.x IP address and also on a 172.x OpenVPN address.
The problem is that when Kamailo receives a call from the VPN and
forwards it to the Asterisk server on it's 103.x address,
Asterisk never
sees the call.
If Kamailio receives a call from the VPN and forwards the call
to the
Asterisk server on it's 172.x address then it works. However, if the
call isn't from the VPN then forwarding it to the 172.x address
doesn't
work. So basically the problem is going between the real network
and the
VPN.
The question is, how can we make this work when calls are
received on
either network on the Kamailio server and are forwarded to Asterisk?
Using ngrep on the Asterisk server we see that it does receive the
INVITE, but Asterisk's logging shows no sign it at all. We guess
it's a
Linux networking issue rather than Asterisk's fault, but don't know
where to fix it. We do have net.ipv4.ip_forward = 1 on both the
Kamailio
and Asterisk servers.
Thanks in advance for any help.
The ngrep on the Asterisk server:
U 2014/01/17 13:15:15.599557 172
<tel:15.599557%20172>.x.x.x:5060 -> 103.y.y.y:5060
INVITE sip:[email protected]:5060;__transport=udp SIP/2.0.

172.x.x.x is the Kamailio server's VPN address
103.y.y.y is the Asterisk server's real address
192.z.z.z is the calling phone's LAN address
