Yes, I completely agree.
Also, I am well aware of what a VPN is and how it functions, but as I said in my original post I would like to avoid using it. I am trying to achieve a functionality similar to what TeamViewer does, but now it seems that the easiest way to do that would be through a regular TCP socket connection over application-configurable port numbers.

socket_connect - Initiates a connection on a socket
SYNOPSIS
bool socket_connect (resource $socket, string $address, [int $port])
DESCRIPTION
Initiate a connection to $address using the socket resource $socket, which must be a valid socket resource created with socket_create(3).
PARAMETERS
o $socket
-
o $address
- The $address parameter is either an IPv4 address in dotted-quad notation (e.g. 127.0.0.1) if $socket is AF_INET, a valid IPv6
address (e.g. ::1) if IPv6 support is enabled and $socket is AF_INET6 or the pathname of a Unix domain socket, if the socket fam-
ily is AF_UNIX.
o $port
- The $port parameter is only used and is mandatory when connecting to an AF_INET or an AF_INET6 socket, and designates the port
on the remote host to which a connection should be made.
RETURN VALUES
Returns TRUE on success or FALSE on failure. The error code can be retrieved with socket_last_error(3). This code may be passed to
socket_strerror(3) to get a textual explanation of the error.
Note
If the socket is non-blocking then this function returns FALSE with an error Operation now in progress.
