Dual Wan failover using P2P microwave connection and site to site VPN
l4tran last edited by
I have two sites which are 1km apart. Both sites are connected using a P2P Microwave connection. Site A is connected to Fiber internet, Site B shares internet through P2P to Site A. On a good day everything is fine. Occasionally, the Microwave P2P connection breaks down due to heavy rain, snow or humid condition, as a result Site B goes offline. Currently, both sites use Juniper SSG5 as the firewall.
-Site B will get its own dedicated Fiber connection with a different ISP.
-Site A and B will then be connected through OpenVPN.
-The Microwave P2P connection will be used for failover.
-Lan1 can have internet access as well as access to Lan2.
-Lan2 has no access to internet or Lan1
-Of course Junipers will be replaced with pFsense routers.
-WAN Fiber ip: x.x.x.x/32
-Microwave ip: 192.168.101.1/24
-Lan1 ip: 192.168.1.1/24
-Lan2 ip: 172.16.1.1/24
-Wan Fiber ip: y.y.y.y/32
-Microwave ip: 192.168.101.2/24
-Lan1 ip: 192.168.11.1/24
-Lan2 ip: 172.16.1.2/24
How can all this be achieved using pFsense routers.
-Looking online, I can probably get OpenVPN to work.
-I can probably get the failover to work.
-Not sure how to get Lan1 to communicate with Lan2 on both Sites
