I have VPN server and I have approximately 500 customers and all of them using same username/password credential to connect my VPN server but connection issues starting after connecting 250 users to VPN server.

How can I increase the limit of concurrent connections? (There is no load on the server)

Configure the server with more available IP addresses with for example


for 1024 addresses.

  • I am using this: rightsourceip= and I will try

  • a /24 is 256 addresses which is close to the point you report having an issue.
