ifconfig is fine.
but a "ping -s XXX -M do" with XXX > 548 (576 with the headers),
hasn't any answer,
although I can see much bigger packets when I dumping while browsing...

I mean, it worked for windows, not for Linux event if I set the mtu to 1500

I tried severals values on the 3G interface (500-1500), nothing worked,

I'm using a 10.x.x.x IP on a "point to point noarp multicast"  link

Well, happy new year!

than the 3.3.0 (even in ADSL) to establish the display connection? ;)
