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. Will let you know if this is the problem. rgds, -- Peter Galbavy Knowledge Matters Ltd. http://www.knowledge.com/ ----- Original Message ----- From: "Ryan O'Connell" <ryan () complicity co uk> To: "Peter Galbavy" <peter.galbavy () knowledge com> Cc: <nanog () merit edu> Sent: Tuesday, January 23, 2001 12:10 PM Subject: Re: clue for the clueless please

Tested with multiple browsers (lynx included ;) and all the same.What does telnet to port 80 reveal? If you can get short queries back (E.g. HEAD / HTTP1/0) but not longer queries it sounds like a PMTUD problem. Does the new customer have Frame Relay or any other links with MTUs less than 1500? Windows sets the DF bit on outbound packets, and I believe Microsoft filter PMTUD ICMP packets. -- 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
