Charles;

I thought it was just me, but you're absolutely correct - M$ seems to
have taken ping ability away from all of their websites. But until I
completed stopped (rather than disable - used "#chkconfig --level 12345
iptables off"), I wasn't able to get past the leaf. Once I ran this
command and rebooted, I was able to ping past the LEAF to the i-net, and
using Mozilla, able to browse using ip rather than name.

I'm now going to apply your suggestion concerning placing the Comcast
name servers in  /etc/resolv.conf.

Thanks again,

Earl
