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 icmp6 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 and my packets never get send! 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, or normal, behaviour under 4.5 when connecting to an IPv6 enabled site.
