Need Additional "Global VPN Client" Licenses for EoS TZ 215?

Hi,

Q 1: I’ve got an old TZ215 at work which came with 2 “Global VPN Client” licenses and we purchased 10 more licenses (back in 2016). Now we need to add 10 more licenses to the firewall but when I tried to register it on mysonicwall, it said the product is past End of Support and can no longer be registered. Is it possible to get additional Global VPN Client licenses for an EoS device (without registering) or do I have to upgrade the hardware?

Q 2: While browsing specs for other brands (Fortigate, Sophos and Huawei), I saw that the majority allow hundreds or even thousands of VPN connections before you need to add licenses. Is this also possible with newer SonicWall firewalls or do their base devices still come with just 2 licenses?
