Hello,

I hope someone can shed some light on to this because I'm at a loss.

I have a small LAN going on at home: a Debian box acting as a firewall 
(external interface gets its IP address from DHCP and the internal address is 
192.168.0.1); a Linux/Windows box that has no problems (only has one NIC in 
it); and then my workstation. My workstation is a Linux Mandrake 8.1 box with 
two NICs in it. The IP addresses assigned to the NICs are 192.168.0.10 (eth0) 
and 192.168.0.11 (eth1). Class C mask.

This is the problem: when I have both NICs enabled network access is a total 
joke. I can get around the internal subnet just fine, but the firewall laughs 
at me when I try to get out to the Internet. Not only that, my whole system 
slows down considerably when both NICs are enabled. If I disable eth1 I can 
get out just fine and my workstation is much more responsive.

I don't think this is a problem with the firewall because I am letting 
everything on 192.168.0.0/24 out. But I am at a loss for words as to why this 
happens when I have both network cards enabled. 

My modus operandi for this is to run VMware. I have set up a bridged 
networking configuration where the virtual ethernet adapter is bridged to 
eth1. OF COURSE, when I have both ethernet adapters enabled AND I start up a 
virtual machine (with an IP address in the 192.168.0.50 range) it works 
flawlessly. If eth1 is disabled, no networking in my virtual machine (which 
makes sense...)

There is something that I am not understanding here. Can someone please shed 
some light on this before I go insane? Thank-you oh so much...

-Chris
