What could be wrong here?

MACHINE #1:
CONNECTION TO INTERNET - works great:
/etc/hostname.fxp0	inet 65.169.21.162 255.255.255.248 NONE
/etc/mygate		65.169.21.161 

MACHINE #2:
CONNECTION TO INTERNET - works great:
/etc/hostname.xl0	inet 205.162.11.165 255.255.255.248 NONE
/etc/mygate		205.162.11.161


But then I put a 2nd NIC card (fxp0) in each box,
put a cross-connect cable between them, and do this:

MACHINE #1:
/etc/hostname.fxp1
inet 10.0.0.1 255.255.255.0 NONE

MACHINE #2:
/etc/hostname.fxp0 
inet 10.0.0.2 255.255.255.0 NONE


... and they just won't talk to eachother.

I've gone over faq6 and man route and man netstat
as much as my little brain can handle.

I've checked cables, connected the same cards to different
networks and all that works fine.

Anyone have any advice just by looking?
