01:21:33 <sommerfeld> warden: as a datapoint I'm using ipf with both v4 and v6 but not doing NAT on v6 and haven't seen crashes like this.  
01:35:11 <nomad> I am curious why use NAT on IPv6?
09:16:20 <warden> So I guess that's related to the use of NAT for IPv6, as referenced in the bugs pointed out by jclulow. I need to use NAT with IPv6 because my datacenter provider assigned me only a single IPv6 address, so I assigned a few ULA to zones on that host, whose services are then published on the Internet by ipfilter.
09:19:49 <m1ari> warden: have you tried asking the datacentre if they can provide more IPv6 addresses or maybe even some allocation.
09:21:10 <m1ari> that is part of the design of IPv6 that there should be enough space to easily provide plenty of addresses and/or allocate a block of subnets.
09:48:45 <warden> eheh, I know... in fact I was a bit surprised they assigned me a single address... I'll ask to their support team, but in the mean time the only way to go is NAT66 :S
16:02:15 <nomad> IIRC, the minimum IPv6 allocation is supposed to be a /64. They specifically do not want artificial scarcity.
16:31:24 <SarahMalik> Standards and reality are two separate worlds.
16:43:19 <m1ari> one of these decades maybe the majority of providers/DCs etc. will have caught up. My first dabblings with IPv6 code was only 1/4 of a century ago (tutor on one of my courses was involved in IPv6 in those early days)
17:57:18 <tsoome_> :D my first IPv6 experience was Solaris 7 and 6bone;) 
18:09:32 <m1ari> way back I used to use an Ultra5 with Solaris 9 (or maybe 10) as my main IPv6 router / firewall (Linux didn't have stateful IPv6 filtering at that time). I can't remember if I also did IPv6 on the previous sparcstation 2 (that was fun to get booted if it was ever switeched off)
