Private port
There is a link for a private port that allows you to change the address. The IP changes only when it is necessary (but not more often than once each 150 seconds). How to change my private port IP address?
For the best user experience, we recommend using separate port for each user.
How does the private port work is shown in the video below.
It is worth considering, if one port is used by several users at the same time and one of the users changes the IP, the IP will be changed for each of the users connected to this port. To prevent this, each user must have his own private port.
Backconnect port
The multiport does not have a link. The IP changes automatically with each request. (as shown in the video below)
Backconnect is primarily used for processes automation and is usually not suitable for regular web-surfing.
