Yes, we found that it doesn't work easily. I don't know the details, but our sysadmin advised against it. We created different 10.x.x.x subnets to use both NICs in one box, which worked fine. I would think there's some advanced magic that could be brought to bear, but we didn't find it. John > regards > > marc >
