I have experience setting up Windows Server 2003, 2008/r2, 2012/r2, 2016/r2 with various roles and configuring them with tailor made solutions for employers. I have worked with multiple Firewalls/Gateways including different versions of Sonicwall, Fortinet, Mikrotik, Unifi etc., setting up site-to-site VPN from on-premise to data-center or On-premise to Cloud environment such as Microsoft Azure, AWS and Google Cloud. I follow a 2 fold process before configuring / setting up VPN connection. First i evaluate the network design of on-premise/data-center such as network addressing, gateway/firewall model, open ports / firewall rules, access / permissions. Second step in process is designing / configuring firewall and testing the connectivity completely. I use tools such as lastpass or Keypass for exchanging sensitive information such as passwords etc., and recommend my clients to in those tools which can be controlled and is secured. I will start the work, once i received the necessary information and i am available for communicating any doubts or queries during day time or evenings.
Let me know if you like my proposal.
