It's just certain WWW sites that don't work. Sometimes I see broken setups: a www server that has path MTU discovery on with a packet filter just before it that filters ot icmp messages to the server. If you want to get pages from such a system and anything between you and that system has a smaller MTU than the servers MTU you're toast. If you are behind a low(er) MTU leased line you can try and set the MTU large enough and see if the problem persists. -Guido To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
