Yes i do, even when using OpenVZ with a bridge setup.

I also have VPNs which get routed into various bridges.
The host plays firewall here.

Well, it is no problem to reactivate kernel support for

a case off uhh my firewall does not work.

May i suggest adding a note to /etc/network/interfaces about
network stack kernel tuning?

cheers
