I have one of these units and need your help. It is operating fine, but I can't seem to log in remotely - not using port 80 for html (yes, I tried selecting administrator using right click), can't access it using port 5550, all I get are errors. I haven't tried updating the firmware - unfortunately I only have access to this on the weekend, so will try it coming up - but would appreciate any help you can give, especially on the port numbers I need to register for port replicating.
