I am just mucking around before getting rid of the device because it can't bridge any connections. I was hoping I could SSH in, but the port isn't open.

Thanks Joerg!

Understood. I was trying to do something with the device as it came DOA and the manufacturer would not help. 

I was trying to SSH into the device but I can't only port 80 is open on the webserver and thats it. All the info I got on the device is by running NMAP and logs from the device itself.

Not sure if this is helpful.

From the device ->
