Mixed up NICs

Hi all.

I've just started building a NAS, and after a few hiccups now have OMV installed with a Asus P5Q Deluxe motherboard.
When I first installed OMV, I had the 2nd Ethernet port disabled in BIOS; no worries there.

I have since run into a situation where I want a gigabit link straight to my main PC, in addition to the existing link to my 10/100 network. I turned on the 2nd port in the BIOS and it was picked up fine.

I'm having an issue though, where the interfaces are mixed about sometimes in the configuration. I have attached a screenshot below:

I have Eth0 configured to DHCP, and connected to the main network. It worked fine originally, and I did not move the plug when adding the second port.
Eth1 has a static address, and was connected directly to my PC.
After one of a few reboots (I think), it appears the interfaces have swapped as I could not connect through the main network until I swapped the connections. In the screenshot it shows I'm connecting to 192.168.8.109, but the link lights on the web page show me connected to the port assigned with 192.168.8.10.

I don't know how to explain it very well, but does anyone know what might be going on? (I'm a Linux noob, but have experience with network stuff)

Thanks.

Ahh bugger.... I've just had my motherboard cark it, so I can't do any troubleshooting at all. I'm now using a board with only a single ethernet port, so I guess it's resolved for me in a way.

Should I mark it resolved, or is it still worth some discussion?
