-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I updated a border gateway yesterday from a Feb 23 kernel to a May 2 version kernel/world, and lost my connectivity to my gif0 HE tunnel. I've been using the following in /etc/rc.conf successfully for some time to establish the tunnel: # Hurricane Electric v6 tunnel ipv6_enable="YES" gif_interfaces="gif0" gifconfig_gif0="[MY V4 ADDRESS] [HE V4 ADDRESS]" ifconfig_gif0="inet6 [MY V6 ENDPOINT] [HE V6 ENDPOINT] prefixlen 128" ipv6_defaultrouter="[HE V6 ENDPOINT]" # v6 gateway ipv6_gateway_enable="YES" ipv6_network_interfaces="internal" ipv6_prefix_internal="[MY V6 /64 prefix] rtadvd_interfaces="internal" Two problems: * That seems to configure the tunnel, but it appears as 'tentative'. * the v6 EUI64 address on interface internal is not assigned as before gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1280 tunnel inet [MY V4 ADDRESS --> [HE V4 ADDRESS] inet6 fe80::211:2fff:fe46:6347%gif0 prefixlen 64 tentative scopeid 0x8 inet6 [MY V6 ENDPOINT] --> [HE V6 ENDPOINT] prefixlen 128 tentative nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> options=1<ACCEPT_REV_ETHIP_VER> connectivity to HE's v4 endpoint is fine, but I get nada for my own addresses: $ ping6 2001:470:a:bd::2 PING6(56=40+8+8 bytes) fe80::202:b3ff:fe97:59f%internal --> 2001:470:a:bd::2 ^C - --- 2001:470:a:bd::2 ping6 statistics --- 3 packets transmitted, 0 packets received, 100.0% packet loss [root@hellfire src]$ ping6 2001:470:a:bd::1 ping6: UDP connect: Can't assign requested address Destroying and recreating gif0 manually has no effect -- same results. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkve2qAACgkQrDN5kXnx8yYfEQCfcbdK/RHygYkPswnUqJ6tS8/Y v28Ani+9YC2LTLQKkJvXEmC4dOEQBHQp =zAHG -----END PGP SIGNATURE-----
