@M.Oswald271605,

I don't think you'll find anyone in the community willing to do a screenshare and actively work on configuring your firewall. That is something that professional services, a contractor, or something of the sort would help with.

You should be able to do this yourself easily. Log into the GUI on the firewall and utilize the global search function to see if any of the addresses are even in use by your firewall. You may not even have anything that needs to be updated depending on how open/restricted your configuration is.
