The Frey VPN is a virtual private network that makes your device appear as if it is connected directly to the Frey router. This is different from most VPNs which tunnel your traffic.
The advantage is, Frey computers can talk directly to each other while on the Frey VPN, not just to the Frey servers. This allows for things like retro LAN gaming.
