I have a ptp wireless network that spans 20 miles from one location to another. It works great. This is a critical network connection for us. I would like to have a vpn backup in case it should ever go down. How can I make this happen automatically? I use peplink routers and can setup the vpn at that location fine, but if my point to point goes down, how can I fail over to the vpn? Is this obtainable?
Currently I just use the same network subnet for both locations. Because I'm using ptp it works fine. I think I would probably need to set the remote location up as a different subnet or put it on a vlan then whether I'm connected either way it would work. The problem comes in when the network ptp goes down. How do I reroute everything through the vpn I would setup? Would it already be connected? If I had them both up wouldnt I get some routing issues?
At the office I have a peplink balance one router connected to tplink vlan able swtiches. I use a peplink balance 20 at the remote office and the same switches. The wireless connection is handled by ubiquti rocket m5s with 30db gain dishes.
