[NTLUG:Discuss] Internet Sharing in Linux

>From what I've seen.... 
TX packets:0 errors:621 dropped:0 overruns:1 carrier:466
says your using a 10MB nic on an 100MB switch. or vica versa. 
Doesn't look like the same thing with you... but might be. 

Double / tripple check your cables ( Cat 5 ) and make sure that 
your equipment is all doing the right 10/100 or what ever it is 
supposed to be doing.
