Bridges / ebtables augmenting iptables

Hello all,

Has anyone played with ethernet bridging with bridges/ebtables rate limiting and shaping augmenting iptables handling firewalling on a cpanel box?

I've had great success doing this in the past buliding kernels with full netfilter support compiled in (including ebtables + friends), it would also be a convenient way to balance multiple nics with different priorities, and port priorities on multiple bridges.

I'm going to play with it regardless, but wondering if anyone else has had any issues? I don't think there would be any, but thought it prudent to ask. Sometimes issues like to hide for a week or two :)

Thanks :)
