OpenVPN tunnel between GWR-HS router and OpenVNP server
Overview
OpenVPN site to site allows connecting two remote networks via point–to–point encrypted tunnel.
OpenVPN implementation offers a cost–effective simply configurable alternative to other VPN technologies.
OpenVPN allows peers to authenticate each other using a pre–shared secret key, certificates, or
username/password. When used in a multiclient–server configuration, it allows the server to release an
authentication certificate for every client, using signature and Certificate authority. It uses the OpenSSL encryption
library extensively, as well as the SSLv3/TLSv1 protocol, and contains many security and control features. The server
and client have almost the same configuration. The difference in the client configuration is the remote endpoint IP
or hostname field. Also the client can set up the keepalive settings. For successful tunnel creation a static key must
be generated on one side and the same key must be uploaded on the opposite side
OpenVPN configuration
Open VPN is established between one central locations and three remote locations with Geneko router configured
in TCP client mode. Authentication used is pre-shared key.
