SSL VPN Global settings and User Authentication static IP Address

Hi,

accordingly to the docs: https://doc.sophos.com/nsg/sophos-firewall/19.0/Help/en-us/webhelp/onlinehelp/AdministratorHelp/RemoteAccessVPN/IPsecSSL/SSLVPN/RAVPNSSLSettings/index.html

it should be possible to assign static IP addresses to SSL VPN users.

I've found the checkbox to enable Static IP address under SSL VPN Global Settings:

(redacted fields in the above screens for security reasons)

(if I check the box I get a subnet mask /25 though)

But I I head to the Authentication - User section, I cannot find the place where to assign the static IP Address:

(SSL VPN Policy field redacted for security reasons).

I'm on XGS107 (SFOS 19.5.3 MR-3-Build652)

Any help would be greatly appreciated.

Thanks a lot.
