I'm hoping someone can assist or point me in the right direction.
Here's the scenario:
Our company has 4 Offices one of which is of coarse HQ; each one of 3 branches have a Untangle FW installed and configured; our HQ has 2 Untangle FW's, one of which is used purely for web traffic and the second for VPN and mail which is connected on a diginet line, the other is on ADSL.
Current configuration for all sites is that all Untangle FW's are configured as OpenVPN servers allowing any one of my users access from anywhere.
What I would like to achieve is to setup a site to site VPN for all my branches. Ideally HQ would be configured as OpenVPN server and my 3 branches as clients. With this being said I would like all my users in all my branches to be able to access data from any of the 4 file servers.
So, like this:
A --> B B --> A
A --> C C --> A
A --> D D --> A
B --> C C --> B
and so on and so on.
So, can anyone help?
