[Users] Question regarding OpenSER behind NATs with NATed clients

[Justin Pearce]

Hi,

I figured that if the proxy was behind a NAT that it would need port
forwarding. But, if the clients are behind different NATs, is there
anything special that needs to be in place, aside from port forwarding
on their firewalls? If the clients are able to determine their own
public IP addresses, is there anything I still need to do to ensure that
INVITEs and BYEs get to the right place (like NATHELPER and RTPPROXY or
MEDIAPROXY)?

I'm trying to figure which direction I need to go with this before I
start to do something, only to find that I needed to go the other way
with it.

Thanks,
Justin Pearce

Hi,

if you place the proxy behind a NAT, I think you need to do a port 
forwarding for the 5060 port - otherwise the proxy will not be reachable

from the public internet.
