I have HW V.A2. Firm 1.15. I currently have 16 virtual server rules defined. When I try adding a new one, via a wired connection, the device reboots. If I try deleting one, it reboots. I have tried upgrading to 1.20, 1.21 1.23 and all of them tell me that they uploaded and to wait 69 seconds for the process to complete, but when the router comes back up, it's still on 1.15. Help!
