Really?  I don't see how you've come to that conclusion.  192.168.0.1
looks like a fairly good next hop address.

If you need redirects, you probably also need to rethink the network
configuration.  Redirects are a bad thing, plain and simple.

Port forwarding and filtering have nothing whatsoever to do with
redirects, as far as I know.

"ifconfig bnx0 plumb"

I don't think you should do that, of course.  I was responding to the
other poster who suggested that reinstalling the system was potentially
a "fix" for having misconfigured an Ethernet interface.

It looks to me like you've actually go everything right, except for the
expectation of redirects.

What is in /etc/resolv.conf and /etc/nsswitch.conf?  Is it possible that
you're just having a problem with DNS?
