Hello all,

I'm getting this across a bunch of bridged tapx interfaces on my network:

0blade038~/tunnel# tcpdump -i tap9

There's one user connected to each tap interface in the bridge, with tap1 being 10.10.0.2, and so on. There are no clients connected on the interfaces corresponding to x.x.x.13, 14 or 15 at the moment.

I'm pretty sure this is a very basic bridging issue, I've had a dig around through Google and not come up with anything conclusive.

If someone could point me in the direction of a fix I'd be grateful :-)

If you need more information, please ask and I will provide it off-list.

Thanks,

Jan
