Round Robin DNS and VPN Servers

If you’re using a VPN server to allow employees to remotely connect to your corporate network and you have a lot of remote users, you can improve performance by deploying additional VPN servers. Rather than divide up your employees into different groups who use different VPN servers, just use one DNS name like create multiple DNS records that map this name to the IP address of each VPN server. This will leverage the round-robin feature of Windows DNS servers, and the result will be that client VPN connections will automatically be load-balanced between your servers as your DNS server cycles through their IP addresses during successive name resolution queries.
