Problem connecting a NAS to en1

[VinceH]

I have a Mac Pro/10.6.4, and a new Synology DS210j NAS. The NAS has been configured hanging off of a router connected to en0. Now I'd like to connect it directly to en1 to get additional bandwidth. I configured en1 in the "usual" way, giving it the address 192.168.0.22. The NAS was configured with the static address 192.168.0.20. When I connect it WakeOnLan can sees it and shows it awake, but the Mac Address field is blank.

A ping results in Request timeout for icmp_seq 0, and ifconfig shows

en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
ether 00:17:f2:03:f1:a1
inet 192.168.0.22 netmask 0xffffff00 broadcast 192.168.0.255
media: autoselect (1000baseT <full-duplex>)
status: active

Any ideas about what I'm not doing right?

TIA, VinceH

what is the adress of your main port ?
You mean you are connecting the NAS without switch with a cross cable ?

If your main Eth is 192.168.0.XX for exemple your other Eth should be another subnet or it wont work
ex: 192.168.1.XX

Thanks for the response. I'm connecting them directly -- no switch. Gigabit interfaces don't need crossover cables. But your second observation worked. When I put one on 0.xx and the other on 1.yy I'm good.

Thanks, VinceH
