Ser nat to yes, as externip set the wan ip of the route, localnet set 192.168.150.0/255.255.255.255 and try again.

But in my system WAN IP is not equal PUBLIC IP.
Ok will apply your suggestions.

Wait, what?

Are you saying that your PBX is behind two firewalls? If so, that’s cool, it’s just really unusual and an enormous pain in the okole to get working reliably.

So, the world needs to know how to get to your PBX. The public address for the outermost firewall is what you’d use in the “WAN” address in your SIP settings. You MUST be using NAT for this to work.

This tells the people you talk to that the way back to your PBX starts at “the WAN” address.

Your public firewall has to port forward 5060, 5061, 10000-20000 to the intermediate firewall. That firewall needs to port forward the same ports to the PNX (or next firewall, repeat as necessary).

This will get convoluted and hard to keep track of, and will probably not perform very well in the long run, but it is theoretically possible.
