Problem with MessageBox Servicev2 from Internet

[jw1001]

Do you have that port forwarded to the TV? The TV will need to be on a fixed address.

If its working via internal network messages, than it needed to work with internet messages too.

It works me well through internet too. Open 52235 port on router (you`ve done it) and forward it to local TV`s IP, port 52235 (you haven`t done it i think).
Yuo can test your configuration by entering your external IP in MessageBox V2 and trying to send. If you get success - NAT port forwarding works well, if not, check your router settings.
