This shows that UDP packets from the Novra are making it to eth1,
but the 'bad length' messages on so many packets indicates that
there is something wrong. At this point, I would try rebooting
the Novra to see if the 'bad length' messages go away.
Question:
- can you use 'cmcs' to talk to the Novra?
If yes, what are the outputs of:
show traffic <- this will show DVB packets accepted and # uncorrectable
errors
show device <- this will show the firmware version
show pids <- this will show the PIDs that the Novra is configured for
show lan <- this will show how the Novra is configured for LAN

The easiest way to test to see if the firewall is blocking traffic is to
turn it off; restart the LDM.
re:
> Any suggestions?
The errors shown in your tcpdump.out listing are troubling. I think we need
to figure these out first then move on to the next step.
re:
> Thanks!!!
No worries.
Cheers,
Tom
