Well, if you've never worked with IPv6 before, it takes a little time to get used to it. It took me a little time, too, and I certainly don't know everything about IPV6 yet. > > My home ISP doesn't support native IPv6 yet (though they > > say they're working on it), but they host a SixXS node, > > so I registered with sixxs.org.

I have a normal DSL line at home, with a dynamic IPv4 address assigned by my ISP. When I re-dial, I usually get a different IPv4 address. That doesn't affect the IPv6 tunnel at all, though. My static v6 subnet is routed to me on my dynamic v4 address (using a gif(4) interface). The sixxs.org people provide a small utility (it's in the ports collection, too) that sets up the tunnel and everything automatically. You only need to configure the address of the sixxs node that you connect to (i.e. the other end of your tunnel). Of course, there are other ways to get IPv6 connectivity. I chose sixxs.org because my ISP hosts one of their nodes, so connectivity is very good. If you're lucky, your ISP provides native IPv6. Only few do right now, but the number is constantly growing. > I my case, my FreeBSD gateway and firewall sits behind the broadband > router, and have private ip's on both interaces (internal and external). > Do I need a public ip on my gateway in order to use a tunnel? In my case, my FreeBSD gateway and firewall _is_ my DSL router. I don't have an external router box, only the DSL modem. Well, maybe the DSL modem could be used as a router, I don't know, for me it's working as a modem only. My FreeBSD gateway machine has a public, dynamic IP address. I think in your situation there would be two options: First, disable the routing and NAT functionality on your DSL box, and do the routing/NAT on your FreeBSD machine, if possible (like I do). The second option would be to use a protocol called AYIYA which can be used to establish a tunnel even behind one or multiple NAT routers. This is supported by SixXs: http://www.sixxs.net/tools/ayiya/ Basically, everyone can have IPv6 connectivity. There is no excuse. ;-) Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
