Hi Nick

Unfortunately i am not able to add an a network adapter in this unit as i have already used the spare slots for additional SATA cards.
I have 12x SATA drives in this unit.

The reason i am pointing the finger at ClearOS, i might be wrong, is that on the LAN port i can transfer files at close to 1Gbps, but on the WAN port i struggle to get 30Mbps.
I even :Swapped" the ports, use the WAN as LAN and LAN as WAN, and the speed issue stay on the WAN side.
Both ports use the same driver. Or am i missing something?
