Greetings all stable people... I have the following very frustrating problem when upgrading to 4-STABLE (cvsupped several times today to make sure, but that didn't change). My box is acting as a NAT and web server. Since I rebooted after remaking the world today, it is unable to communicate via the external interface (the web), however: - NAT still works fine (PCs on the LAN are able to access the internet) - pinging works ok too tcpdump and netstat shows nothing interesting (well, tcpdump shows the packet flying to and from, but no reply --- output below). I strongly suspect a hardware problem, but still, this is strange. Please Cc replies to me as I am not getting mail for my subscribed address for now. -- Chive PS: Output from tcpdump: Direct connection from external box: 02:47:06.238063 20-230.CampusNet.ucl.ac.be.1037 > 20-231.CampusNet.ucl.ac.be.smt p: S 1498602663:1498602663(0) win 16384 <mss 1460> (DF) [tos 0x10] 02:47:09.231648 20-230.CampusNet.ucl.ac.be.1037 > 20-231.CampusNet.ucl.ac.be.smt p: S 1498602663:1498602663(0) win 16384 <mss 1460> (DF) [tos 0x10] NAT Connection from a computer on my lan: 02:47:16.904041 20-230.CampusNet.ucl.ac.be.30003 > 20-231.CampusNet.ucl.ac.be.sm tp: S 4129596323:4129596323(0) win 16384 <mss 1460> (DF) [tos 0x10] 02:47:16.941262 20-231.CampusNet.ucl.ac.be.smtp > 20-230.CampusNet.ucl.ac.be.300 03: S 2489143898:2489143898(0) ack 4129596324 win 17520 <mss 1460> (DF) 02:47:16.941614 20-230.CampusNet.ucl.ac.be.30003 > 20-231.CampusNet.ucl.ac.be.sm tp: . ack 1 win 17520 (DF) [tos 0x10] 02:47:17.009978 20-231.CampusNet.ucl.ac.be.1109 > 20-230.CampusNet.ucl.ac.be.aut h: S 2489188137:2489188137(0) win 16384 <mss 1460> (DF) 02:47:17.010234 20-230.CampusNet.ucl.ac.be.auth > 20-231.CampusNet.ucl.ac.be.110 9: S 1501637353:1501637353(0) ack 2489188138 win 17520 <mss 1460> (DF) 02:47:20.001167 20-230.CampusNet.ucl.ac.be.auth > 20-231.CampusNet.ucl.ac.be.110 9: S 1501637353:1501637353(0) ack 2489188138 win 17520 <mss 1460> (DF) 02:47:20.030193 20-231.CampusNet.ucl.ac.be.1109 > 20-230.CampusNet.ucl.ac.be.aut h: S 2489188137:2489188137(0) win 16384 <mss 1460> (DF) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
