Sounds like hooie to me:
sysctl -a |grep ttl
net.inet.ip.ttl: 68
I don't know if it helps with AT&T, but in order to convince Cogeco's DHCP
server to play nicely, I've had to set the following in
/etc/dhclient.conf:
interface "ed0" {
send dhcp-client-identifier MAC_ADDRESS;
}
where MAC_ADDRESS is a MAC address that had successfully received a lease
previously.
You're not behind a firewall perchance?
HTH,
