By default, all Perimeter 81 accounts include access to our 36 global server locations. With our servers, the outgoing IP address is shared amongst several accounts simultaneously. These IP addresses rotate periodically. Public Servers are advisable if you need a VPN connection.
You can purchase a private server for your team members who can share a single static outgoing IP address, which only is accessible by your organization. This creates the opportunity for many security capabilities which are only possible with a static IP address. For example, remote users can always connect to the gateway first, then have their IP address whitelisted to a security group in AWS.
