@damianstelmach Ok, do you use controller or stand alone? why 80 and 443 is open is a mystery. to get it stalth disable Block TCP Scan with RST, in controller you do that in network security and...

@damianstelmach I do a scan from a ER706W with this result and no open port

@damianstelmach Try a scan from here https://www.grc.com/x/ne.dll?bh0bkyd2

@damianstelmach it's not open if you haven't opened these ports, my best guess is that you're testing against the wan ip from the lan on the same router.

@pur_berger it sounds like you get the same IP on the WAN as you do have on the LAN. try changing the LAN ip to e.g. 10.43.1.1/24 before connecting to the WAN

@OmYudhanto I have one outside, this winter it was -30 degrees for over a week. no problems
