ARP REQUESTS ISSUE NEED FIX

Hello I'm having a server with a VPN client installed on it my server is creating a lot of broadcast traffic by doing arp requests all the time for internal ips, I need someone able to log in to the server and fixing this issue asap after the project is given to you without affecting the functionallity of the VPN. If you are not sure about this please don't show interest for this project I need the right guy the very first time, And I can't afford any misstakes made that will affect the functionallity. I got all the logs (Ip: s doing the riquests etc) needed for this job. Sincerely
