Do you mean that GnomeMeeting crashes or that you don't *receive* video
anymore after a few minutes?

99% of the routers that support H323 do not support Tunneling and fast
start, you should disable both of them. If you have to enable IP
translation, then your router is not configured to support NAT and that
explains the video problem, packets go out, but do not come back.

If the router supports NAT, you can not forward ports.
If the router doesn't support NAT, then you have to forward the ports
like indicated in the FAQ and enable IP translation.

Do things in a logical way:
- either your router support NAT, in that case, do not forward ports,
disable IP translation, fast start and tunneling
- or it does not support NAT, in that case, forward 1720, 30000-30010,
and UDP 5000-5003 and enable IP translation. If can not forward
30000-30010, but only 30000-30005, then you can do it but you have to
modify the /apps/gnomemeeting/general/tcp_port_range to 30000:30005 and
restart GM
