Hey,

The card in the proxy/gateway with ip 10.0.0.100/255.0.0.0 is: Intel 
Corp. 82557/8/9 [Ethernet Pro 100]
The second card with ip 192.168.254.100/255.255.255.0 is: 3Com 
Corporation 3c905B 100BaseTX [Cyclone]

 From the ifconfig output it shows both cards with only one address 
each, plus i allways thought you cant have move than one card using the 
same IP as it would conflict ?

Any more ideas on where this problems might lay?

Thanks again
Grant.
