Time Warner IPv6 pains
Posted 04-23-2013 at 01:17 AM by rocket357
I asked TWC about ipv6 a while back, and the tech I got on the phone was as clueless as they come. Oddly, I could see router advertisements with link-local address (modem playing games, or so I thought), so I fired up rtsol and cried as it failed repeatedly.
A bit later, I noticed that with the kids competing for bandwidth and my wife gaming, we were starting to saturate the 20 Mbps we were getting. I call TWC and upgrade to the 50 Mbps package.
Then something peculiar happened. Still getting router advertisements, but now, I can pull a global ipv6 addy on my OpenBSD firewall!
Joy of JOY! I can ping ipv6.google.com from the firewall! Time to roll out ipv6 to my home network!!!
Then I notice they gave me a prefixlen of 128. Correct me if I'm wrong, but basically they said "no, you can't have a block of ipv6...but we'll give you just ONE ipv6 ip to get your hopes up".
Urgh. I hate you sometimes, TWC.

After a few calls and discussions with TWC, I've determined that they have no intention of changing their policy for prefixlen 128. So I've setup a hurricane electric ipv6 tunnel and will test that out instead, and migrate to a more open-minded ISP as soon as possible. Sucks, but that's how it goes sometimes =)Posted 04-28-2013 at 04:30 PM by rocket357
