So, OpenVPN is a good option for setting up a VPN server because it’s open-source. Server administrators would need to manage a VPN server and client configuration for each user. Solution: In this case, we can use a VPN server to gain access to a company network. So, IP will always rotate as users will have to contact server administrators each time they change network. There is no static IP for a normal broadband connection. This means their public IP will change whenever they switch networks. By disabling public access and using firewall rules, managing users’ public IP can be really hectic because users usually don’t stick to a specific network. Then the server administrator can whitelist that IP address providing access to the user.Ģ. If someone wants to access a server, they’ll have to contact the server administrator and provide them their public IP address. Solution: In that case, we can disable public access & use firewall rules or security groups to manage users’ public IP’s. But what if websites don’t need to open globally or do not need public access? In some cases companies allow users to access servers via the internet without any specific condition which means servers have public IP & are publicly available. Therefore, we will discuss a few aspects of network access & their drawbacks:ġ. These things have their own set of complexities. Meaning, they first need access to that particular server either via a public network or using VPN.
