Log in to Vifib and find the Get Freefib Token on the side menu of your Vifib Dashboard. Freefib tokens are a custom extension in Vifib to directly use the Re6st based IPv6 network gateway provided by Vifib. Click the Get Freefib Token button and wait(!) until you are forwarded to the Freefib hosting subscription page.

Allocating the resources associated with a FreeFib token will require 10+ minutes. Refresh the page after a while and wait for the actual token to be displayed in the Configuration Parameters ("xxxxxxxxx" in the screenshot). You can add a short title to this hosting subscription to better identify it in case you are using multiple Vifib services. Copy the token. Before going back to the terminal, click on Services in the side menu.

Note, that if you are using this FreeFib token, you must use the the Freefib registry (http://re6stnet.gnet.erp5.cn/). So if you want to use the single line Re6st installer, make sure to use the installer in the gnet/ folder (meaning: https://deploy.erp5.net/gnet/re6st) when later installing Re6st on a machine with this token (it will have the correct registry URL).

The token you have requested is actually an allocated computer partition on one of the servers of Vifib with specific re6st software installed. If you look at the information provided with your token, you can see that a Freefib token is enabling access to another SlapOS node providing the type of services you are using - in this case, the IPv6 gateway to communicate with other Freefib nodes.
