Barix Instreamer 100 Port Forwarding on U-Verse 5268AC

Anyone have any experience with port forwarding on a U-Verse (Pace) 5268AC for a Barix Instreamer 100?

I am able to see the device on the LAN and have set up a TCP port, but I'm not sure it is getting through the firewall.

Without a lot of other details here, if you have any experience, please respond and I will explain further.

Thx.
