Allow Telnet to server behind a Sonicwall

How do I setup a Sonicwall TZ300 to allow me to telnet into a server on the local lan behind the sonicwall?

On which port(s)?

You should just be able to set up port forwarding but you need to know what you're going to Telnet into and on what port that service is listening in order for that to work. Bear in mind that you're about to punch a hole in your security. It would be more advisable to setup a VPN instead.

The user is logging into a very old Alpha Micro Server through telnet on port 23.  I would like to setup a VPN to get them in.
VPN is definitely the way to go. We have a TZ300 at work with VPN services enabled but I cannot remember off the top of my head how it was originally configured. I can get back to you tomorrow when I can look at the VPN settings.

In the meantime, either of these YouTube videos might be of some help:

The first is standard VPN setup. The second is SSL VPN.

I have setup an SSL-VPN and it is working. My concern was the old server being maintained. I know the VPN is the most secure and just jumped in and got it setup.  Thanks for your help.
So your issue is resolved now?
