Not specialised hardware as such, I've just not been able to reproduce
it outside of this specific operating scenario.
I can't trigger it with empty firewall rules as it relies on a DNAT to
occur. If I try it directly to the internal IP address (as I have to
without netfilter loaded) then of course nothing fails.
It's a pain in the bum as a fault, but it's one I can easily reproduce
as long as I use the same set of circumstances.
I'll try using 3.0-rc2 (current git) tonight, and if I can reproduce it
on that then I'll attempt to pare down the IPTABLES rules to a bare minimum.
It is nothing to do with ebtables as I don't compile it. I'm not really
sure about "bridging firewall" functionality. I just use a couple of
hand coded bash scripts to set the tables up.

Not specialised hardware as such, I've just not been able to reproduce

I can't trigger it with empty firewall rules as it relies on a DNAT to
occur. If I try it directly to the internal IP address (as I have to
without netfilter loaded) then of course nothing fails.
It's a pain in the bum as a fault, but it's one I can easily reproduce
as long as I use the same set of circumstances.
I'll try using 3.0-rc2 (current git) tonight, and if I can reproduce it
on that then I'll attempt to pare down the IPTABLES rules to a bare minimum.
It is nothing to do with ebtables as I don't compile it. I'm not really
