How do I setup OpenVPN Access Server to use site-to-site?

If you want to have two access servers connected to each other via site-to-site you will need to have gateway functionality enabled somewhere on the network of one of your Access Servers.

· I will refer to the two access servers we want to connect as AS1 (Access Server 1) and AS2 (Access Server 2).


· Now in order to get a tunnel established between AS1 and AS2 we will need to setup a gateway client on one of the LAN'S for either AS1 or AS2.


· By setting up the gateway client it will connect to a remote access server (AS1) and push the routes from the access server(AS1) to the LAN(AS2) and push its LAN's(AS2) routes to the remote Access Server(AS1).


· If you want an access server on the LAN(AS2) of the gateway client to connect to the remote access server(AS1) you will need to make sure your explicitly state in the User Permissions area of the user that the gateway client connects to the access server(AS1) to push the route of the private subnet of the access server(AS2).

· It will be much easier if you run the gateway client on the same machine as the access server (AS2).
