Xlite connect to CME behind NAT

[koralul2000]

Hello,

When Xlite is in the same network with CME the registration works fine. When I try to connect Xlite outside the network I receive 408 - Request Timeout. The CME is behind NAT so I configure port forward - public 5060 to CME 5060 port, but the same result. With the same port forward configurations and non-Cisco gateway the registration works fine.

Are there any other configurations for CME in order to register Xlite from outside the network?

please provide us with the make and model of you FW as well as config.   did you run wireshark at all on your xlite machine?   what sort of other diagnostics have you performed?
