How to configure site to site VPN in OpenVPN?

I am using OpenVPN server and client in two different routers (WAN links) with a third router which acts as an OpenVPN gateway. The traffic is transferred between the WAN links to my LAN as usual via my 3rd router. But now, I need to configure the client site (in LAN) to get access to the VPN server so that they can share same IP address through their LAN. Is it possible to configure such a topology?
Thanks. I have a similar setup with a VPN Server (OpenVPN), and several clients, all in home LANs. The only difference is that in my case, I'm using client certificates for authentication (the connection between client and OpenVPN server is always encrypted).

First, I define a virtual interface "tun" in my server for each openVPN client connection: // OpenVPN config. Ifconfig tun0 192.168.1 netmask 255.0
I then add this to the OpenVPN server configuration file (which is /etc/openvpn/server.conf in my setup): ifconfig-push 192.2 tun0 Now, because all of my clients are in home LANs, I have each client connect to its own OpenVPN server. I do this by adding the following line to each client config file (/etc/openvpn/client.conf in my setup):
Redirect-gateway def1. The client will connect over a virtual interface (tun0), using the address 192. You'll need to change that address to match your own home network setup, if you use client certificates (as I do).

As far as setting the IP address, etc., this is done at each OpenVPN client, normally under the ipv4-method section. As I said before, I use client certificates, so I define the "client certificate option" there:
Ca ca.crt cert client.crt dh1024.pem key client.

Can OpenVPN be used for site to site VPN?

I want to create a VPN that has the following properties: I want to connect from a server in the US to a server in China (and possibly other locations). I don't want to use an exit node. I want to use a company's VPN, not my own VPN software. Is OpenVPN capable of meeting those criteria? If not, what VPN software is capable of meeting those criteria? OpenVPN can be used for site to site VPN. There are several free and paid clients available for download, including the client I use.

It can be done with openvpn. See this tutorial. It is possible to have a company server (the "client") that you use for all your connections and then connect that server to the sites you want to access (the "server").

I have a server that I can SSH into.

What I need to do is access OpenVPN (running on my dedicated CentOS 5 server) via the same connection. So instead of typing "vpn.test.com" I want to type "sshusername@vpn. Is this possible?

When using the openvpn v3 API you can specify an alternative remote endpoint and auth mode in the connection string: remote.net Description: Alternate hostname for OpenVPN access server. The format of this parameter is a fully qualified name of a network. connection for which your VPN server has been configured, eg. 'server.net', etc. This option can be used with the HTTP mode
authentication method for clients to connect to the OpenVPN server. Auth.type=machines Specify the type of credentials that are allowed for access to the VPN. This option requires user names and passwords that have been configured in the system. configuration file (see openvpn.conf(5)). To enable this
option, edit the system-wide configuration file, and add the. following lines after 'auth.userv1.userv2.userv3' line:
. username = user. password = pwd. . I was finally able to connect via URL like I wanted to. I was able to find a tutorial for that on my own by searching for "openvpn url". Now I know how to do it. So instead of posting every step here I am posting the final product here. So if anyones needs it they can skip the steps that I posted here.tar.
