Thanks

so you are not able to access web interface, correct? Try to connect to XG using command line, option 4 then type:

system appliance_access enable

Now you should be able to access XG using web interface. Remove the rules that locks you out and re-type the command:

system appliance_access disable

"This command will restore the Appliance Access settings as per configured in System >Administration>Device Access.
Check that appliance is accessible only from specified IP addresses or ports as per your configuration after performing the above command."
