Concurrent user site licenses
Access to concurrent user site licenses is based on the IP range we have been provided by your organization. Access is not allowed if you are not connecting to the website from the network range we were provided. You can include the IPs for your VPN or proxy server in the range for access and that will allow users to access via that service.
If you have users who work remotely off your network range and do not use a VPN or proxy server, you can assign them an individual login account. For each individual account you assign, the total number of available concurrent users you have diminishes by one. So, if you have a 25-user site license and assign five individual accounts, up to 20 users could access the site concurrently instead of 25.
