That document doesn’t say what layer. But it does say it supports Websockets.
Just odd that when I try to set it up using a named tunnel I don’t get an option to specify the WS service type. However it does require a service type if you want to connect to it.
Looking at this page it would seem that it’s a layer 7. Although I could be wrong, but my front end app has issues finding my backend service for websockets.
Granted I even tried to connect to my private computer using other protocols. I couldn’t get through. Anyway I’m most likely going to be taking that project offline soon.
Probably should sue the town for violating 1A rights.
Right wingers love to pull that one out of their arse, would be funny to see them trying to cope with that.
