a clean, expanded version of your script that supports four trading routes:

✅ London
✅ Singapore
✅ Frankfurt
✅ Hong Kong

You can now Allow one route and Block the other three, OR clear all rules.

✅ What This New Script Supports

✔ London

✔ Singapore

✔ Frankfurt

✔ Hong Kong

Use Case Example

If user selects 3, the script will:

• Allow Frankfurt

• Block London

• Block Singapore

• Block Hong Kong

Automatically resolves IPs every time → no stale firewall entries.
