Hi all, im hoping to be pointed in the right direction here.
What im looking for is a way to establish a VPN that will simply never go down.... ever! here is the scenario:
i have 2 sites, and i control both ends, lets say two offices; head office and office 1. Head office has two internet options, both fibre from two different isp (its backbone internet, ultra stable) plugged into some rbxxx.
Now office 1, can have a multitude of internet connections, for now its 4g and 3g.... plugged into a rb750.
I'm looking to connect these two offices with a eoip or vpn or something. my understanding was that you cant really bond the vpn, but you can bond a eoip... i still don't get how this helps, the illustration shows the eoip is made in a 10 range ip... where i need to connect over general internet... so what would my 'remote' address would be? the head office live ip?
What im hoping to achieve is that the VPN can use all internet (when its good), or just the one if the other is down. And if i get a 3rd, i can just add it to the mix, making it faster, and more stable.
there is surprisingly little documentation on this... i would have thought inter-office vpn is very common.
