config as an exit of IPv6 over IPv4 tunnel
Can I configure FreeBSD as an exit of IPv6 over IPv4 tunnel? Let me explain it in detail. Both hostA and hostB have global IPv4 address. And hostA has global IPv6 address. I have installed FreeBSD 7.0 on both hostA and hostB. Then, I want to config IPv6 over IPv4 tunnel from hostB to hostA. Is it possible? -- Hashimoto Kouki [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I have a similar configuration for my IPv6 connectivity. There are some alternatives (stf(4), faith(4)), but this is based I what I have. This is mostly in terms of what you'ld add to /etc/rc.conf on HostB -- HostA will be similar, but addresses will be reversed in the obvious places. i) Create a gif(4) interface and configure the endpoints: gif_interfaces=gif0 gifconfig_gif0=hostB-ipv4-number hostA-ipv4-number ii) Enable IPv6 on HostB -- I'm assuming you've assigned a /64 net block to HostB (perhaps a tad excessive, but pretty much the default for an allocation of a chunk of IPv6 address space.)

Note: it's pretty easy now to make HostB an IPv6 router and assign IPv6 addresses to anything on the same local subnet as HostB. In fact, you can use rtadvd(8) on HostB to make that automatic: ipv6_network_interfaces=auto ipv6_prefix_em0=1234:5678:9acb:def0 rtadvd_enable=YES rtadvd_interfaces=em0 Then just run rtsol(8) on all the other machines that will use HostB as their IPv6 gateway.

Thanks, Matthew ! I will try it, and report again. 2008/7/21 Matthew Seaman [EMAIL PROTECTED]: Hashimoto wrote: Can I configure FreeBSD as an exit of IPv6 over IPv4 tunnel?

FreeBSD 4.11 IPv6-over-IPv4 tunnel problem
Hi List, I want to establish an IPv6-over-IPv4 tunnel to my ISP. After some hours trying i got myself acounts at HE and XS26 for testing and they work. My Setup is FreeBSD 4.11-STABLE with ip(6)fw (stateful) and natd running. My ISP gave the appended setup information which is for Debian Linux (which i've never used). The IPv4 endpoints are 217.197.85.214(me) and 192.109.42.23(ISP) the IPv6 endpoints are 2001:bf0:c00c::c00c:0002:2(me) and 2001:bf0:c00c::c00c:0002:1(ISP). I asked my ISP for support but they don't know the way for FreeBSD and they tell me the tunnel is definitely working. I tried doing the following but this and several other approaches did not yield anything : zwelf:~# ifconfig gif0 create tunnel 217.197.85.214 192.109.42.23 up zwelf:~# ifconfig gif0 inet6 alias 2001:bf0:c00c::c00c:0002:2 zwelf:~# ping6 ff02::1%gif0 PING6(56=40+8+8 bytes) fe80::250:bfff:fe58:6c75%gif0 -- ff02::1%gif0 16 bytes from fe80::250:bfff:fe58:6c75%gif0, icmp_seq=0 hlim=64 time=0.746 ms 16 bytes from fe80::250:bfff:fe58:6c75%gif0, icmp_seq=1 hlim=64 time=0.422 ms 16 bytes from fe80::250:bfff:fe58:6c75%gif0, icmp_seq=2 hlim=64 time=0.427 ms ^C --- ff02::1%gif0 ping6 statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max/std-dev = 0.422/0.532/0.746/0.152 ms Thanks for reading, any comments appreciated Leon /* /etc/network/interfaces for a Debian system */ auto zwelf6 iface zwelf6 inet6 v4tunnel address 2001:bf0:c00c::c00c:0002:2 netmask 112 local 217.197.85.214 endpoint 192.109.42.23 ttl 64 up ip tunnel change zwelf6 ttl 64 up echo 1 /proc/sys/net/ipv6/conf/all/forwarding up ip -6 route add2001::/3 dev zwelf6 down ip -6 route delete 2001::/3 dev zwelf6 /* full ifconfig */ rl0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST mtu 1500 options=40POLLING inet 192.168.10.1 netmask 0xff00 broadcast 192.168.10.255 inet6 fe80::250:bfff:fe58:6c75%rl0 prefixlen 64 scopeid 0x1 ether 00:50:bf:58:6c:75 media: Ethernet autoselect (100baseTX full-duplex) status: active rl1: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST mtu 1500 options=40POLLING inet6 fe80::230:84ff:fe0b:15d4%rl1 prefixlen 64 scopeid 0x2 ether 00:30:84:0b:15:d4 media: Ethernet 10baseT/UTP status: active lp0: flags=8851UP,POINTOPOINT,RUNNING,SIMPLEX,MULTICAST mtu 1500 lo0: flags=8049UP,LOOPBACK,RUNNING,MULTICAST mtu 16384 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x4 inet 127.0.0.1 netmask 0xff00 ppp0: flags=8010POINTOPOINT,MULTICAST mtu 1500 sl0: flags=c010POINTOPOINT,LINK2,MULTICAST mtu 552 tun0: flags=8051UP,POINTOPOINT,RUNNING,MULTICAST mtu 1492 inet 217.197.85.214 -- 192.109.42.172 netmask 0x inet6 fe80::250:bfff:fe58:6c75%tun0 prefixlen 64 scopeid 0x7 Opened by PID 70 gif0: flags=8051UP,POINTOPOINT,RUNNING,MULTICAST mtu 1280 tunnel inet 217.197.85.214 -- 192.109.42.23 inet6 fe80::250:bfff:fe58:6c75%gif0 prefixlen 64 scopeid 0x8 inet6 2001:bf0:c00c::c00c:2:2 prefixlen 64 -- gnupg key ID: 9B820836 Fingerprint: 6081 8F41 8FEC 0D69 DB98 F014 0FD4 B47D 9B82 0836 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Since most ISPs are still IPv4 only you have to resort to tricks like the IPv6-IPv4 tunnels to access the 6bone. It will not 'work properly', until all the equipment IPSs use is upgraded to IPv6. In the meantime you can play with IPv6 by getting a tunnel like those freenet6, Hurricane Electric and others provide.

The key point here is that the backbone needs to support IPv6 for it to work. If your ISP's backbone doesn't know IPv6, then it won't get routed, even if the kit they use is capable of handling it. You can tunnel IPv6 between widely distributed sites using the gif(4) and faith(4) pseudo-interfaces.
