Reverse VPN
Introduction
OpenVPN Server needs a port forwarded and open to function. Many times this is not possible because of firewall restrictions. This is where “reverse VPN” comes in handy.
The other application of “Reverse VPN” is multi site connections. With “reverse VPN” many remote locations can be connected to form one effective LAN.
Requirements
- The Gargoyle OpenVPN server location have the correct port forwarded and open (Firewall access).
- Suitable Gargoyle routers
Installation
Set up routers as per “Site to Site” How-to
Server
This is a good server setup
Note: You need to select “Credentials are specific to each client”
Clients
Each client(s) must be setup correctly
The really important part is “Subnet behind client”. This is the LAN where the client is being placed.
If “No Subnet Defined” is selected you will effectively have a one way connection e.g. Client to server
Network Example
“LAN Host 2” can ping “LAN Host 5”
Ping 192.168.45.x
The same address can be used many services, one example being “remote desktop”
