All of the info I've seen on the web points to having (2) Ethernet ports, and the hardware I'm using is a 1U server box with just 1 Ethernet port on board. If transparent mode can be done with 1 Ethernet port, any specifics on how to do it would be much appreciated. Sure. You can either use VLANs or multinetting. The latter is not very clean, and would give a networking engineer fits, but it works. Whether it's viable only dipends on your particular environment. In general going transparent is not really a nice thing to do, as it makes things complicated. But in the end only you can know if it's the right thing for you. -- /kinkie
