Getting Internal port number xxx does not match external port number xxx on all ports running the firewall checker. Sonicwall is managed by another vendor who said they have configured everything as stated in the 3cx document. However, they have an updated firmware that does not contain the port remap option. Could this be the reason? and do they need to downgrade the firmware. I've called into 3cx support multiple times and cannot get anyone to call me back. Now just getting straight to their voicemail.
