I just installed 7.3 on one of my machines at home.  The box sits behind a
firewall (Smoothwall) which is connected to my cable modem.  The machine
gets its IP (from the Smoothwall) using DHCP.  When i go to register my
system using rhn_register, I get a "No route to host" error.  I am able to
ping some websites (yahoo, google) but not others (redhat,microsoft).  I
can't seem to figure out the problem.

Here's some info:
*gatekeeper (route output below) is the name of my firewall/router.  It has
an entry in /etc/hosts.

Can somebody please tell me what I'm doing wrong?

Thanks,
mike
