I did STF on this issue and I became more and more confused.
Here is my issue I installed a Vertical Xcelerator IP and I want to use the IP phones outside of my network I thought this would be a simple task but it is not with SIP.
I was told by Vertical that UDP port 5060 and UDP port range 35000 to 65000 needs forwarded and 1:1 NAT needs setup. I have no issue with the port forward but the 1:1 NAT stumps me I also have read that advanced outbound NAT may do the trick.
And just an FYI I have a dynamic public IP that never changes I have had it for over 2 years I have read that 1:1 NAT does not work with dynamic IP's now to make this more complex I would like to subscribe to a SIP provider for a SIP trunk and make this work after getting the external IP phone working external.
Here is my network setup
external 207.255.XXX.110/24
internal 192.168.78.1/24
Ip PBX 192.168.78.30
If there is anyone that could help please do.
Thanks
Jeremy
