IPv4-DHCP ist not the real problem, I'd not even need it in this
usecase. IPv6 is causing the headaches as netfilter-folks refuse to
implement IPv6-NAT for net mapping because 'IPv6 renumbering is easy'.
However, there is a static IPv6 address for permanent internal use and
to be able to access the outside, one would need 1 address from each
uplink range. With static assignments in /etc/vservers/*/interfaces this
is a big hassle. That's why I check netns, which works fine with IPv6,
but gives me trouble with IPv4.
Wouldn't it be for the changing uplink IPv6 prefixes, everything would
just be fine.
