3 ports? wow you lucky.
on my tests if i even forwarded 1 port the superhub started having routing issues but ok I give in as mine didnt lock up.
I did have that time it wouldnt boot up for a few hours tho.
I can confirm the lan traffic reboots for sure, I only had to send a 100meg file over my lan and it rebooted. when I forced a 100mbit lan speed it was ok tho but couldnt max out the speed, my dir615 out performs it on 100mbit connection speeds. on gigabit its less than half the throughput of my billion 7402nx and self rebooted.
