Enter a hostname or an IP address and comma separated ports to check those ports status. Click on the Start menu, type CMD in the search box, then right-click on it and select Run as administrator. Open Port Checker tool can be used to check if a port is online or not.

You can specify a host name, IPv4 or IPv6 address. Step 1: There are two ways to open the command line. IPv6Scanner is a port scanner that allows you to probe a server for open, closed or filtered ports. Now it's likely that you have issues with your prefix changing, hopefully not too often, but maybe if your power goes out for a day when your internet comes back up you have a new ipv6 prefix, so you'll want to check and edit this rule after such events. This method is very useful if you want to take a quick look at the ports used.

Suppose 2002::1 is your router, and 2002::2 is the server on your LAN you want to make available to the world, then create a new forwarding rule in LuCI, from WAN to LAN, click add and edit, select ipv6 family, allow any address in WAN to access 2002::2 on the destination port you choose with action 'accept' Please provide a Hostname and a port number to check. Port 'forwarding' where packets destined for the router's IP are instead rewritten and forwarded to a private IP on the LAN side is not necessary under ipv6, what is needed is simply to open up the firewall to allow forwarding traffic to the public IP of the server as there are plenty of public addresses to go around for everyone (times several thousand trillion)
