Cannot access Linux Web Page or ping linux server from different subnet.

I have two nic's in my linux web server: 150.150.32.104 and 150.150.32.105.
They are both on the same subnet: 255.255.254.0.

the .105 is set up in DNS... I can not ping or access the web server from
another subnet across a sysco router.

Am I stupid for having two nic's on the same subnet or what? All client
pc's are NT 2000.

Thanks,

Frustrated Newbie.

Yes you are. IIRC Networking-HOWTO (http://www.tldp.org/ and search for
'networking') explains the concept of subnets rather well.

The fundamental reason why not to have two NIC's on the same subnet is that
your routing tables will get confused. Very confused. Of course, there are
situations when it is possible and even necessary to use two NIC's with IP's
on the same subnet (or even the same IP!), but these are advanced stuff from
LARTC (Linux Advanced Routing & Traffic Control, http://www.lartc.org/)

It probably won't have the result you expect. Traffic coming in on .105
will probably be responded to on .104 so if you are trying to achieve
load balancing it won't work.

But it should not stop things working altogether. What does the routing
table show (netstat -rn)? Can you ping .104 remotely?
