+# Firewall
+
+This file explains the [firewall.sh](https://git.kska.io/notkshitij/scripts/src/branch/main/firewall.sh) script and why things are the way they are.

+
+## What?
+
+- `firewall.sh` is a shell script for automating firewall setup on my laptop.
+- I was tired of manually modifying the rules every time I was on a different network so I created this script.
+
+## Working
+
+1. The script shows 4 options and takes input for options from 1-4 in the `optn` variable.
+2. It uses switch case for executing commands based on selected option.
+3. Option 1 -> Home profile
+
+	- This profile is used when connected to my home network.
+	- By default all options begin by deleting the existing rules. Since I only have 4 rules max, I have used for loop from 0 to 5 (I'm aware it loops 5 times.)
+	- I did not use `sudo ufw reset` because it resets all the rules and deactivates the firewall which I did not want happening in any case.
+	- Then, it sets the default rules to allow outgoing traffic and deny incoming traffic followed by printing the output.
+	- I have then specified rules for allowing incoming traffic on port range 1714:1764 (TCP and UDP) for KDE Connect, ports 22000 (TCP) and 21027 (UDP) from `192.168.219.0/24` (my phone's IP range) for Syncthing.
+	-. Lastly, it reloads the firewall and prints the verbose status.
+
+4. Option 2 -> Public profile
+
+	- This profile is used for any network other than my home network.
+	- Again, it begins by deleting any existing rules.
+	- Then, it sets the default rules to allowing outgoing traffic and deny incoming traffic.
+	- Lastly, it reloads the firewall and prints the verbose status.
+5. Option 3 -> Panic mode
+
+	- This profile is for rare cases where I don't want any network traffic coming in or going out.
+	- It begins by deleting any existing rules.
+	- Then, it sets the default to deny incoming and outgoing traffic.
+	- Lastly, it reloads the firewall and prints the verbose status.
+6. Option 4 -> Exit
+
+	- Exits the script
+
+7. Default
+
+	- For any other option number, it prints a message and ends the execution of the script.
+
+8. That's it!
