Accessing Synology terminal via webmord?

Question

linux

Synology is in a remote LAN. It can be accessed via quickconnect.to.
How can I start the terminal from there (from the web console).
The purpose of this: From synology, connect to the router via ssh, which only lets you in from LAN.
There were old threads on the Internet about the shellabox module, but, as they say, it doesn’t work anymore.
There is nothing in the official "Packages" according to console, ssh and terminal. There is Domotz Network Monitoring. Works using port 3000, but does not plow through quickconnect.to:3000 - only from LAN (I checked this on another synology near me).
That is, you probably need a third-party package that will give the web console to synology, provided that the connection comes from the Internet via quickconnect.
Could you recommend options?
PS SSH access is enabled.
Thank you!

Answer 1

vpn - and in the future it will solve many other problems
by the way, the same Synology has a whole VPN Server in applications (did not try it)

Answer 2

Alternatively, do not use Synology Access. Instruct the user of one of the remote LAN computers to install Teamviewer, connect to the remote desktop via TV, use the same Putty to access the router via ssh, working from a remote computer.
