many [UDP bad checksum ...] messages

["Wojciech Ziniewicz" <wojciech.ziniewicz@gmail.com>]

Hello,
I'm having many messages like that :


My router is 217.17.31.1 and serves 256 public IP adresses (with DNAT/SNAT) :

Nov  9 11:50:37 beta printk: 1 messages suppressed.

This is an 20mbit traffic internet router with pppoe server and about
500 other dhcp wireless clients. There's no "advanced" routing ..

p.s. kernel 2.6.15 with imq and p-o-m

Moreover - clients report that sometimes they cant contact with the
client provisioning panel that is located on router ...

Am I wrong , or it is just a broken NIC ?
