how to use reverse vpn

Post by atrac »

Hello
I have read some posts about this topic. However, my question is not about how to setup it through menus, but instead about how it works.
My problem is that I discovered that the 4g router that is before the gargoyle router is too difficult to modify and apparently is blocking access from outside to the gargolye, as I need remote access (I am using dynamic dns).
Now, to overcome this, I have read that I could use reverse vpn.
My understanding is that in this case the gargoyle will connect to somewhere through a VPN, but that means that I have to setup a server with a fixed IP? My intent was of course to control the router from my home PC, but I do not understand what to do on this side...

It will solve your problem but you need full network control of one end (server end)

You need two sites (or more)

Site 1 Server
Site 2 Client
Site 3 Client
etc

On the "server site" you need full port control

ok, I understand. But, let's say Site 1 is my home: I have a dynamic IP, so I could use a dynamic DNS service and install openVPN on my router.
How does the client (gargoyle) on site 2 gets the IP address of the server from? Can I write somewhere the nameserver so that site 2 will be able to resolve it through the dynamic DNS provider? This is the most obscure part for me.

I have a dynamic IP, so I could use a dynamic DNS service and install openVPN on my router.
2 options

1. Fixed IP address
2. dynamic DNS service

On Gargoyle you need to setup dynamic DNS service first then OpenVPN will find the address automatically
