Hey /g/ quick question about ports.
Assuming the following is true:
A port is pretty much just an address a process is listening for incoming traffic on.
If you set up a server nothing is forcing you to use any specific port even though standards suggest you use certain ports like 80 for http.
If I set up a FTP server and set it to listen on port 80 instead of 21,
Could I connect to it and use it as an FTP server over port 80 if I was behind a router that blocks all ports but 80?

...if the router doesn't do DPI and realize you're not doing HTTP

You don't even need ports, you can just route your traffic trough dns or whatever.
That's how my VPN setup is working
