SoftEther VPN User Forum

I was reading this over: https://www.softether.org/4-docs/1-manu ... P_Routing)

And it seems that the location hosting the L3 Switch is the single point of failure, if that goes down, none of the locations can contact eachother, is there a better design?

With VRRP, the default gateway can be made redundant.
You can avoid SPOF by installing two pairs of SoftEther VPN tunnel for each route to redundant routers.
