How we can change the portal url https://passthrough.fw-notify.net to another, e.g. https://passthrough.mydomain.com? We have a wildcard certificate for a domain like *.mydomain.com and want it upload this to the Sophos UTM. Before iOS vers. 11.x we could confirm this private certificate for https://passthrough.fw-notify.net. With 11.x it is not possible, iPads disconnect from an open wlan with this website-authentication.
Because we have many guests, we cannot desire to import the ca-certificate on each device to have wlan.
Thanks Heiko
