Firewalling IPv6 - an easy way?

[Chris Boot <bootc@bootc.net>]

All,

I've been running IPv6 locally without much trouble at all. Now I'd like 
to build a firewall on my router and had a good look around for debian 
packages for IPv6 compatible firewall software and I came up blank. I 
currently use Shorewall for IPv4 and it works really nicely but there 
clearly isn't any support in that for IPv6. I see there's a 6wall that's 
based on Shorewall in LEAF/Bering, but it's really old and not packaged. 
I'd rather not have to build my own rules using ip6tables if possible.

Many thanks,
Chris
