Use a non-default telnet port

[tareco]

Hi everyone,
Is there a way to use an alternative port other than tcp/23?
Thank you.

It's possible to implement such support but to what end? Why do you need to use a non-standard port? I haven't encountered a firmware version that allows you to change which port its listening on.

It's actually a networking challenge, I am reaching to the device through port-forwarding and I don't have access to map port tcp/23.

This is not a good idea - telnet is unencrypted. Personally, I'd vote against this feature as you should be setting up a VPN in order to access the main receiver.

@JonGilmore I understand that telnet is unencrypted and the fact I am using a VPN to secure the connection is actually what motivates my request. Unfortunately the control server cannot forward tcp/23 directly as there are multiple devices in the network that need to be addressed, ending up in a situation where all I have is port-fw. Basically the control server sees a common peer VPN IP address and equipment selection would be done by mapping each tcp/23 to another tcp/1024+ port.
