Hi Mike,
The authentication failures that you're seeing relate to media player trying to access streaming media (554-RTSP, 1755-Microsoft streaming).
Normally connections out from your LAN wouldn't be blocked, but it looks like you're using a public IP address range on your LAN. WinGate has seen this IP address (90.0.0.*) on the WinGate adapter and firewalled it, so connection attempts through WinGate from that IP address are blocked.
You should consider renumbering your LAN so that you are using a private IP address range (we recommend 192.168.*.* but you can also use 10.*.*.* or 172.16.*.*).
If you don't want to renumber your network then change the setting for the adapter so that WinGate treats the adapter as an internal adapter.
