The tunnel-setup goes fine, I can ping everything without a problem. But when I open an interactive session, after a short time weird things happen: The tcp-session itself goes fine, until the moment my machine starts sending out tcpmp6 neighbor solicitation requests: tcp-session setup: 19:46:39.452386 mavetju-k7.tsps1.freenet6.net.1761 > ftp6.netbsd.org.ftp: S 1971097502:1971097502(0) win 65535 19:46:40.077770 ftp6.netbsd.org.ftp > mavetju-k7.tsps1.freenet6.net.1761: S 4240147676:4240147676(0) ack 1971097503 win 32768 19:46:40.077880 mavetju-k7.tsps1.freenet6.net.1761 > ftp6.netbsd.org.ftp: . ack 1 win 33220 220 ftp6.netbsd.org FTP server (NetBSD-ftpd 20020201) ready. 19:46:40.767713 ftp6.netbsd.org.ftp > mavetju-k7.tsps1.freenet6.net.1761: P 1:63(62) ack 1 win 33120 [flowlabel 0x80114] 19:46:40.867511 mavetju-k7.tsps1.freenet6.net.1761 > ftp6.netbsd.org.ftp: . ack 63 win 33220 the weird neighbor solicitation packets: 19:46:44.697259 mavetju-k7.tsps1.freenet6.net > ftp6.netbsd.org: icmp6: neighbor sol: who has ftp6.netbsd.org 19:46:45.697183 mavetju-k7.tsps1.freenet6.net > ftp6.netbsd.org: icmp6: neighbor sol: who has ftp6.netbsd.org 19:46:46.697131 mavetju-k7.tsps1.freenet6.net > ftp6.netbsd.org: icmp6: neighbor sol: who has ftp6.netbsd.org user anonymous 19:46:47.201295 mavetju-k7.tsps1.freenet6.net.1761 > ftp6.netbsd.org.ftp: P 1:17(16) ack 63 win 33220 331 Guest login ok, type your name as password. 19:46:47.897276 ftp6.netbsd.org.ftp > mavetju-k7.tsps1.freenet6.net.1761: P 63:112(49) ack 17 win 33120 [flowlabel 0x80114] 19:46:50.147087 ftp6.netbsd.org.ftp > mavetju-k7.tsps1.freenet6.net.1761: P 63:112(49) ack 17 win 33120 [flowlabel 0x80114] 19:46:55.196847 ftp6.netbsd.org.ftp > mavetju-k7.tsps1.freenet6.net.1761: P 63:112(49) ack 17 win 33120 [flowlabel 0x80114] 19:47:05.256189 ftp6.netbsd.org.ftp > mavetju-k7.tsps1.freenet6.net.1761: P 63:112(49) ack 17 win 33120 [flowlabel 0x80114] 19:47:25.234907 ftp6.netbsd.org.ftp > mavetju-k7.tsps1.freenet6.net.1761: P 63:112(49) ack 17 win 33120 [flowlabel 0x80114] 19:48:05.212334 ftp6.netbsd.org.ftp > mavetju-k7.tsps1.freenet6.net.1761: P 63:112(49) ack 17 win 33120 [flowlabel 0x80114] These tcp-packet never gets acknowledged! After having done several tests, with ftp, ssh and plain telnet, everything goes fine until just after the neighbor solicitation. But icmp-traffic, even large packets as 4Kb, go without a problem. FreeBSD 4.4 doesn't have this behaviour. Can somebody please confirm that they have the same behaviour under 4.5 when connecting to an IPv6 enabled site before I make a fool of myself on -hackers?
