Looks to me that you're missing a default route.  This can be added
manually with the command:

% route add default gw 192.168.1.1

I don't know the redhat'ism, sorry.

You should also check your /etc/resolv.conf for an entry pointing to
192.168.1.1 as your DNS, or to your ISP's DNS server.  "man resolv.conf"
can give you help with this.
