Purchased new in 2015. I used it for about 3-4 years back then. After that, I put it away as a spare when I replaced my router. I think there's a security risk with IPSec these days, so it's probably best not to use it. I updated the firmware to the latest version for this listing, reset it, and checked the operation of all ports, including USB. However, I didn't use the console management port, so I don't know if it works. IPSec/VPN-related functions have not been verified. Please understand that I am not liable if they don't work properly. The reset button needed to be held for about 30 seconds when the Diag light was green during startup (a little different from the manual). If, by any chance, some of the LAN ports are not recognized, I will consider a partial price reduction depending on the extent of the issue. I cleaned it briefly. There are minor scratches and scratches/peeling on the front panel protective sheet, but overall, the appearance is in good condition. I've marked it as "Used - with scratches and dirt" considering its age. No original box. No AC adapter included. It will be wrapped in bubble wrap and shipped via Takkyubin Compact.
