- More links:
Earlier, your host could have no more than 2,500 links; now, 10,000.


- Connection server auto-selection:
Now you can turn on the connection server auto-selection from the servers of your Protelion network, and thus ensure continuity of your tasks. If your connection server goes offline, Protelion VPN switches to another one.


- Keeping the connection server selection:
Now you can control the connection server selection mode without entering the debug mode. Turn on the Keep Server option for the coordinator you had selected manually in Protelion VPN to remain your connection server whenever new keys and host links arrive from the management Protelion software. If the option is off, the coordinator imposed by the management Protelion software overrides your current connection server as new keys and host links arrive.
