I'm using Softether VPN Server hosted at Azure VM. There's DNSMasq as DHCP server. All of my clients are using OpenVPN Client.
Unfortunately I have encountered a problem. When the number of connected clients approaches 240-250 there are mass disconnections and problems with connecting devices. When it comes to CPU and server RAM usage, it is very low. I didn't set any limits for connections.
What can be the problem? Is it some of Azure VM limits or maybe something else? When I revoke some of certificates and lower the number of active clients to ~220 then everything is okay.
DNSMasq config:
Code: Select all
interface=tap_soft
dhcp-range=tap_soft,172.16.0.10,172.16.3.250,24h
dhcp-option=tap_soft,3,172.16.0.1
dhcp-lease-max=512
server=1.1.1.1
dhcp-authoritative
