[linux-dvb] Inet via Sat: tcpdump vs. iptraf

[Thomas Kesselheim <linguin@satspeed.de>]

Hello,
I recently encounter mysterious problems when trying to configure an 
Internet-via-Satellite installation with Debian Woody.
I have tried linuxtv-1.0.1 as well as linuxtv-1.1.0 with dvbtune and with szap 
& dvbnet but it is always the same.
I open the network interface and active it with ifconfig -a dvb0_0 
192.168.46.21.
Next I check the arriving packages with tcpdump -ni dvb0_0:
17:30:18.440433 192.168.250.52.44761 > 229.104.117.116.9205:  udp 52 (DF)
17:30:18.454868 192.168.250.37.34716 > 229.104.116.128.9205:  udp 1460 (DF)
17:30:18.454883 192.168.250.53.49933 > 229.104.117.173.9205:  udp 356 (DF)
17:30:18.454906 192.168.250.53.49933 > 229.104.117.173.9205:  udp 1460 (DF)
17:30:18.454917 192.168.250.53.47655 > 229.104.117.241.9205:  udp 404 (DF)

So this seems to work.

But when checking the same interface with iptraf -d dvb0_0, iptraf says there 
is no package arriving at all.

Can you help me? There seems to be some filter activated but I cannot find 
any.
THX.
