|The only suggest I have requires a reboot.|
That suggestion is, try a reset to factory defaults.
The process for that will be in the manual/setup guide that came with the unit. If you don't still have it, check on Linksys' site for the manual. If memory serves me, you press and hold the reset button (with the unit powered on) for 10 seconds and release, to reset to factory defaults.
If that doesn't fix it, I think it's toast.
If you don't wish to risk losing the VPN's I suggest buyin a replacement and configuring it. Bring it into production and take the defunct one out and then try resetting it.
That's all I can think of..........sorry.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
