Yes, we intentionally (for some other reason during testing) set the MTU on the p2p link to 554 - oops. Will get it switched back... Still wondering though - if a normal dial-up has a lower than 1500 MTU, why would they work.
Sounds almost certainly like an MTU problem. Try www.bt.com, if that fails then it's pretty much definite. Microsoft are a bit silly for setting the DF bit on outbound packets, firewalls at web hosting facilities that block all ICMP are even more silly. Why on earth Microsoft, who must know about this problem, block ICMP on their kit I don't know... Most if not all dialup has an MTU of 1500. -- Ryan O'Connell - <ryan@complicity.co.uk> - http://www.complicity.co.uk I'm not losing my mind, no I'm not changing my lines, I'm just learning new things with the passage of time
