Question about clustering and static virtual hubs

Post by maxime » Tue May 10, 2022 2:42 pm

Hi,

I'm new to softether and VPN in general, so I read most of the doc and came up with the following solution for a VPN cluster.

I have a controller with a single cluster member inside a private LAN. I have a single load balancer in front of both machines. This load balancer is the only external IP I have. In fact, I'm going with a cluster and static hubs because I can't have more than a few external IPs in my setup and I need to maximize the number of connections to the VPN. I originally planned on scaling the number of cluster members as I need to increase the number of client connections.

The issue is, I can't get it to work. I can't enable SecureNAT on the hub, I can't get DHCP to work and so the whole thing kinda not works. I even get my client access denied when I hit the cluster member, which leads me to believe I'm completely misunderstanding the cluster and static hub functions.

Is anybody able to clarify these concepts a bit? Maybe help me come up with a way to make the public IP limitation work with a cluster setup?
Thanks!

Clusters servers must be on public IP as well. Cluster controller is not a relay server or a reverse proxy. It just randomly picks a server and sends its address and port to the client.

Got it. Makes sense with what I observed.

Thanks!
