What does mean '20+3 Ports' on the VPS description?

This means that:
» 20 NAT IPv4 ports can be customized directly by the customer, for TCP and UDP;
» 3 ports are automatically pre-reserved by VirtFusion for services provided for the customer, more specifically SSH bridging at port 22 and two others directed at internal Windows/*nix services. 

This also means that SSH bridging does not count towards the customized port range available for the customer, contrary to what used to occur on the previous system.
