A rose by any other name is still a rose. I'd call it a VPN, or at least a proxy.
Running some sort of client on the remote side to accept connections could also work, so the client runs somewhere it can actually accept the random ports.

TELNETD(8) System Manager's Manual TELNETD(8)
NAME
telnetd - DARPA TELNET protocol server
SYNOPSIS
/usr/libexec/telnetd
DESCRIPTION
Telnetd is a server which supports the DARPA standard TELNET virtual terminal protocol. Telnetd is invoked by the internet server (see
inetd(8)), normally for requests to connect to the TELNET port as indicated by the /etc/services file (see services(5)).
Telnetd operates by allocating a pseudo-terminal device (see pty(4)) for a client, then creating a login process which has the slave side
of the pseudo-terminal as stdin, stdout, and stderr. Telnetd manipulates the master side of the pseudo-terminal, implementing the TELNET
protocol and passing characters between the remote client and the login process.
When a TELNET session is started up, telnetd sends TELNET options to the client side indicating a willingness to do remote echo of charac-
ters, to suppress go ahead, and to receive terminal type information from the remote client. If the remote client is willing, the remote
terminal type is propagated in the environment of the created login process. The pseudo-terminal allocated to the client is configured to
operate in "cooked" mode, and with XTABS and CRMOD enabled (see tty(4)).
Telnetd is willing to do: echo, binary, suppress go ahead, and timing mark. Telnetd is willing to have the remote client do: binary, ter-
minal type, and suppress go ahead.
SEE ALSO
telnet(1C)
BUGS
Some TELNET commands are only partially implemented.
The TELNET protocol allows for the exchange of the number of lines and columns on the user's terminal, but telnetd doesn't make use of
them.
Because of bugs in the original 4.2 BSD telnet(1C), telnetd performs some dubious protocol exchanges to try to discover if the remote
client is, in fact, a 4.2 BSD telnet(1C).
Binary mode has no common interpretation except between similar operating systems (Unix in this case).
The terminal type name received from the remote client is converted to lower case.
The packet interface to the pseudo-terminal (see pty(4)) should be used for more intelligent flushing of input and output queues.
Telnetd never sends TELNET go ahead commands.
