I checked on the Windows box, and the pages behave the same way there, so=20
it's definitely not the Mac.
No firewall running on the server, so it's not that.
Here's the routing table:
netstat -rW

traceroute to 66.140.63.124 (66.140.63.124), 64 hops max, 40 byte packets

*traceroute: sendto: Host is down
traceroute: wrote 66.140.63.124 40 chars, ret=3D-1
Here's something odd. If I change the first octet to anything other than=20
66, the traceroutes run normally. But if I leave the first octet at 66=20
and change any of the other octets, they all return host is down. I=20
double checked, and the defaultrouter is 66.221.96.1 in /etc/rc.conf.
