Add CIDR Notation Support for IP Addresses and Subnets

Overview

This PR adds the ability to display IP addresses and subnet masks in CIDR notation throughout the report. The feature is configurable through a new option in the JSON configuration file.

New Configuration Option

{
    "Report": {
        "InfoLevel": {
            "UseCIDRNotation": false
        }
    }
}

New Functions

Added new private functions in Src/Private/Convert-AbrFgtSubnetToCIDR.ps1:

• Convert-AbrFgtSubnetToCIDR: Converts IP/subnet pairs to CIDR notation
• Convert-AbrFgtSubnetMaskToCIDR: Helper function for subnet mask conversion

Modified Files

Get-AbrFgtFirewall.ps1

• Added CIDR conversion for firewall address objects (type: "ipmask")

Get-AbrFgtRoute.ps1

• Added CIDR conversion for:
  • Route Monitor section (ip_mask)
  • Static Route destinations
  • Policy Based Route source/destination subnets

Get-AbrFgtSystem.ps1

• Added CIDR conversion for:
  • Interface primary IP addresses
  • Interface secondary IP addresses
  • Interface remote IP addresses
  • Administrator trusted hosts

Get-AbrFgtVPNIPsec.ps1

• Added CIDR conversion for Phase 2 configurations:
  • Source subnets
  • Destination subnets

Feature Behavior

When UseCIDRNotation = true

• Converts space-separated IP/subnet pairs to CIDR notation
  • Example: "192.168.1.0 255.255.255.0" → "192.168.1.0/24"
• Preserves existing CIDR notation
• Single IP addresses get /32 suffix

When UseCIDRNotation = false

• Maintains original FortiGate format
• Some fields use forward slashes instead of spaces for consistency

Error Handling

• Invalid IP addresses or subnet masks are returned unchanged
• Includes error messages for troubleshooting
• Maintains existing functionality when conversion fails

Testing

• Tested with various IP/subnet combinations
• Verified behavior with configuration enabled/disabled
• Confirmed error handling for invalid inputs
• Checked formatting consistency across all sections

@alagoutte , on a slightly different topic, would you happen to know owner of PScribo? If so, would you be able to see if he could take a look at this pull request for me?
iainbrighton/PScribo#130

This is the enhanced table function I earlier tried to add to this module but then decided that its better to reside higher up stream.
I am waiting on its approval to then incorporate further enhancements to this module (items which are commented out at the moment).

[alagoutte]

No but i will see what it is possible !
