I want to make sure the Slackware Linux edge servers are ready for IPv6 when eventually the ISPs catch up.
We signed up for a free tunnel endpoint with http://www.gogo6.com/freenet6/tunnelbroker/ to try a few things out. Building the gogoc client from source was easy. The edge server was set up as a host, not a router, as my desktops are all IP4 with a black hole gateway route to the outside world and the server is a proxy. It was great seeing this come back:
# ping6 www.kame.net PING www.kame.net(2001:200:dff:fff1:216:3eff:feb1:44d7) 56 data bytes 64 bytes from 2001:200:dff:fff1:216:3eff:feb1:44d7: icmp_seq=1 ttl=49 time=328 ms 64 bytes from 2001:200:dff:fff1:216:3eff:feb1:44d7: icmp_seq=2 ttl=49 time=329 ms
It’s turns out to be fine to use squid proxy 3.1.20 with IP4 clients on the internal network proxied out through an IPv6 address. My IP4 desktops can see the “Dancing Turtle” at http://www.kame.net (proof that they are accessing an IPv6 specific page).
We’ll look at ip6tables another day.
