let get a bit more detailed.
The A400 is programed with and internal and external IP address.
The A400 is behind the firewall/nat (linux box). It connects fine A400 to A200. This is via static routes.
When I removed the static routes from the A400 and the A200 and programed the A200 to use the external IP address of the A400 as its gatekeeper. It registers fine, but when it tries to make a call, the RTP reply addess becomes the internal IP address of the A400.
Has anyone seen this and is there a work around for this. It is getting very crazy adding static routes to 2 A200’s and a A400, so they can communicated with each other.
