dhcpcd-discuss

I got ip6tables working, and tried RC3, but there's little joy in Mudville. (I follow the list here, but I may have missed/forgotten some syntax and other changes.)

The main errors that caught my eye:
  - unknown options
  - wrong iaid on eth3 (I suspect it should be ...7d, but previous versions would only work with ...7a)
  - parse error on ia_pd (?)

Per Smoothwall, eth0, eth1, eth2 are 'internal' nets, and eth3 is internet. ISP is Comcrash and has been happy to give me a /60 in the past.

I hope it's just that my config is outdated.

This conf worked well before (v6 and maybe early v7). I wrote a script that generates the .conf from a template; it uses data it finds in the system or sensible defaults for items not found.
