Every XGS Model suppor up to maximum number of SSL VPN and IPsec Clients...
lets take and example: According to KB-000039345
XGS 2100 support up to 500 concurrent SSL VPN tunnels (is this number for site to site o for clients?? or both ??)
XGS 2100 support up to 2600 concuent IPsec tunnels (is this number for Site to site or for clients?? or both)
Since other brands like Sonicwall include an small number of clients by default (you need to buy licences for more clients if you need more)
How many client for SSL VPN and IPsec VPN support by default ?? is there a official document that certify the default number of clients included ??
the VPN Connections are limited by Hardware-ressources (or Kernel) only. There is no License Limit.
Here you are at the UTM-Forum. For more details ask within XG Forum: https://community.sophos.com/sophos-xg-firewall/

BTW: I would not use or suggested to use Site to Site SSL VPN tunnels. Its outdated tech. Use IPsec and those numbers are for both in terms of IPsec.

Thanks for your comments ... let me clarify something.. i already know that article KB-000039345. that shows the max numbert of tunnels every models support (compre with Sonicwall... the base licence include 2 o 5 clients by default according what type of VPN but up to 1000 clients with other licences)
My question is do i need another licence with XGS to use those max number tunnel supported ??
Those concurrent max number for XGS .. are for site to site tunnels or client tunnel or both at the same time??
Thanks in advance
The VPN Connections are limited by Hardware-ressources (or Kernel) only. There is no License Limit.
... and no License to allow the max possible number of connections
With IPSec the max numbers are for RAS & S2S Connections (as stated by LuCarToni).
If you use other features at the XG ... you have to reduce the possible number of connections.
