These functions have proven supremely useful – I’ve automated a tedious firewall object provisioning process based on your work.. Thanks for sharing!

Rather thank dot-sourcing, I’ve made a Module from the file by adding ” Export-ModuleMember -Function * ” and saving the script as a .psm1 file in the system Modules directory.

Thanks :)

PowerShell 1? It may have some issues with the unsigned integers used by the script, everything was written under PowerShell 2. Otherwise if you happen to have examples of where it’s failing I’ll fix it :)

This is beautiful. I have been doing some of this from scratch and you just saved me a lot of time.

One thing I have noted however is that Int32 can’t handle some of the decimal values generated. Everything works very nicely if you use Int64 instead.
