I have the following entries:

Where 194.35.14.1 is my server ethernet IP, and 194.35.14.2 is my NT
client IP.


And tcpdump -i dvb0 gives entries like:

23:49:03.367122 sr1113.europeonline.net > 237.44.3.17: (frag 46471:1480@1480+)
23:51:40.312216 kc113.europeonline.net > 224.224.4.17: (frag 27086:1144@2960)


Thanks for your help.
