IPv6 Router and NAT/connection tracking

[Internet Protocol version Six <inet6@mail.be>]

Hello all,

I have a box that's configured as a firewall/NAT (IPv4) and router
for IPv6, which is doing it's job fine, well, fine.., IPv6
connections keep timing out, they work for a second or 30 and then
it timesout -> connections, ping6, traceroutes, ... from the
Internet to the IPv6 address behind the router don't work anymore.
Also if I do a ping6 or make a connection to a remote IPv6 host on
the Internet it doesn't work, however if I ping6 the router from the
other machine, everything works again...for about 30 seconds to 5
minutes, and then the problem begins again...

I was told that this is caused by NAT/connection tracking. Is there
*any* solution to this? This is really annoying as I *need* NAT, but
also want to give IPv6 connectivity to other machines on the LAN.

Your help is greatly appreciated.
