Softether cluster members working with Privae subnet

Post by suddhasilsarkar » Wed Jun 03, 2026 2:52 pm

Hi Everyone,
I need some help, I had setup soft-ether cluster in AWS behind NLB. All traffic going into NLB --> softether controller and post authentication the session established with one of the member server in the cluster. In this pattern I had to keep my SE client open communication to the member server's public IP as well ( I had to keep the cluster in public Subnet ). This is a challenge from security standpoint , and some limitation on client side. I would like to know if I am missing anything here, is there anyway i can configure so that client only establish connection with NLB (ip) and no need to open communication to individual softehter cluster's member nodes ?
Thank you for all help as always, and please let me know if any questions.

Thanks
SS

You're asking lots of rhetorical questions.
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.

Limit of users per Hub in SoftEther

Post by suddhasilsarkar » Fri Jun 05, 2026 1:39 pm

Hi Team,
I am coming back again, I could see that 10K user limit per hub is a hard limit, is there any other solution I can use to go beyond 10K per HUB in the Softether VPN server ?
Thanks in advanced for any help around this.

Thanks
SS
