Not on a good day it won't! :-) The filer's networking code should be more than sharp enough to see that it has an interface directly connected to your 151.142.223.0 network and route packets targeted to this network to said interface accordingly. In fact, a "netstat -r" on the console should show you an explicit zero-metric route for each network, directing traffic to the interface on which that network is to be found (look for gateway targets that look like "link#1", "link#2" in the "Gateway" column). ---
That too is what I thought.
*hmm*
The filer can ping itself on 223.30, the router and suns can talk to each other, but thats it for anything else.
Another cable might fix this, but the cable on there now, is new and certified...will test on a working sun server.
