Dear honors
I am facing some problem in port forwarding. I want monitor all Wi-Fi router (TP-link ,tenda, Netgear, Unifi) remotely.
1. I enabled remote management from router using any 255.255.255.255 port 8080

I configured WAN using local IP(Ex: 192.168.62.1) which is connected to mikrotik.
Actually how do i monitor wifi router remotely please give me some instrucition...

Think you shouldn't host any service any other then VPN to the internet.
Monitoring can (with a VPN server) be done the some way as you monitor locally.
