You have a path MTU problem. Somewhere between your gateway and the
outside world is a link with an MTU < 1500, it is probably the
Livingston Portmaster at your ISP that you dial into. Several sites
that should know better block all ICMP so they never see the "need to
fragment" responses. Either push the MTU on your PPP link up to 1500
or change the Ethernet MTU on all your internal boxes to be the same as
your PPP link.
