Hello,

I have the default setup of allowing local traffic to be routed from the host to the LAN. I have two NICs, one connected to the Internet and the other to the LAN.

I have an Xbox 360 on the LAN that connects to Windows Media Center on my Vista box. This all works fine except pause, fast-forward, rewind, etc. all break the stream horribly. The stream uses RTSP, I believe, but I have already disabled protocol inspection on this with no success.

Any ideas?

I have discovered the "problem area" in the extremely large log that gets produced in just a few minutes of video streaming.

Notice how there are lots of to/from UDP packets happily moving around. Then, when I try to move around in the video (rewind, pause, fast-forward), perhaps RTSP but nothing on port 554 here, it dies, sending several TCP ACK, PSH packets. Shortly after these, only UDP packets to the Xbox are sent and the Xbox does not respond back with UDP packets like it was doing in the heathly video streaming portion. Instead, the progress indicator for the current TV show moves all the way back to the beginning of recorded content so far as if the "rewind 15 seconds" command got corrupted by Kerio. The screen then goes black, but I can restart the stream again quickly.

With no firewall and NAT or just simple Windows ICS none of these problems occur, indicating Kerio WF is definitely corrupting my stream.

Any ideas? Thanks Smile

192.168.1.1 = Media Center (Vista)
192.168.1.4 = Xbox 360
"Xerxes Network" = LAN

Normal streaming occurs here...

Something goes wrong in the above conversation and now only UDP packets are being sent to the Xbox 360 with no response back to the Media Center. This continues for a lot longer than shown here until it finally cuts off.
