Dual wan interface active LED

[Speedco]

So i am building a PFsense box with a custom 2u rackmount enclosure + faceplate. I plan to have dual wan ports and would like to have an LED indication that would indicate if the WAN interface is up and forwarding. I have a matrix orbital LCD display for the front of the unit which has general purpose outputs that can drive LED's. As i am new to FreeBSD, before i invest alot of time in learning the OS is this even possible?

Thanks in advance for any replies.

Might be possible with our lcdproc package, not sure if that specific LCD is supported or not.
