RE: good router

["Lee, Steve" <stevelee amgen com>]

This is what i'm trying to do. I have a block of 8ip address.
so far 1st and last is the network and broadcast.
well the other six are used between two machines.
one primary and one secondary nameserver.
the rest is shared for virtual domains for webhosting.

Right now the system is running off a DSL line with the
the modem connected directly to the server using two 
nic cards.  one that goes to the hub and the other
to the DSL modem.  

My concern is if the system with the two nic card goes 
down (hardware failure) I would then loose the connection for
the other computers they would loose the route to the WAN,
can't route out.  I would like to setup a hardware router
to do the job of what the linux box was doing.  
Then if one system fails the other system will still be
able to route out to the WAN?  correct?  

or is there a better way of doing this?
