I believe that is what I did when I configured the NAT virtual servers record in the modem.
But at that IP something must be listening for the can you see me test to work.
There is a device/embedded server on the network at that IP. I know that it is working because an app running on a phone can interact with it.
For example run a webserver on port 80 on one of your computers.
make sure it works from within your network.
I would have to install such a a server on a host PC and frankly that is more involved than I can handle without a bit of a learning curve.
On the router, make sure that computer always gets assigned the same IP from the DHCP server. for example 192.168.1.10
then in port forwarding, set the external port 81 to redirect to 192.168.1.10 on port 80
Then from internet, someone can go to your public ip:81 and will be served by the webserver on port 80 on your computer.
You can also specify it's only for TCP or UDP.
I use that to run a plex server on port 32400 so I can stream movies from my house to my phone.
the router may be running its admin interface on 80 or 443 so you may not be able to forward those ports.
The canyouseeme web utility was specified by the embedded web serving device manufacturer (Insteon) and they led me through a testing process to verify the issue was with the modem.
This was all working until about 6 months ago. I'm unsure if a firmware upgrade was pushed to the modem or if somehow the configuration was changed by sonic without our knowledge. Nothing has changed with regard to the embedded web server.
Is there a different configuration rock to look under?
