Watchguard SSL VPN issues

I encountered an issue with a setting up SSL VPN’s on Watchguard firewall’s.  When using AD integration you need to create a group called SSLVPN-Users as part of the proccess. In this case we wanted everyone to have access so we added Domain Users to the group. This doesn’t actually work, the client connects without errors but you are unable to ping any resources.. You need to specify to users here individually for this to function properly.
