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]

Is it possible? i don't understand why you need single directional tunnel. you need bidirectional transmission of IP packets. man gif ___ 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.) Adjust the prefixlen to suit. ipv6_enable=YES ipv6_defaultrouter=-interface gif0 ipv6_default_interface=gif0 ipv6_ifconfig_gif0=1234:5678:9abc:def0::1 prefixlen 64 iii) Settings on HostA are slightly different -- HostA has to be a router, and it only wants to route the HostB block via the gif(4) tunnel: ipv6_enable=YES ipv6_defaultrouter=hostA-ipv6-gateway-address ipv6_gateway_enable=YES ipv6_static_routes=hostB ipv6_route_hostB=1234:5678:9abc:def0:: -prefixlen 64 -interface gif0 iv) That should be everything you need to get point to point connectivity working. 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?
