 ## Open port 
-- Make sure u have `iptables-nft` installed
+On Arch linux base that using an iptables for default network firewall. I dont want to use it because it suck. So i moves on `Firewalld` 
-- Run script `sudo bash ./.config/iptables_config.sh`
+
+### How are we changing from iptables to firewalld 
+
+1. removing complete iptables: 
+	```Bash 
+	sudo iptables -F
+	sudo iptables -X
+	sudo iptables -t nat -F
+	sudo iptables -t nat -X
+	sudo iptables -t mangle -F
+	sudo iptables -t mangle -X
+
+	systemctl list-unit-files | grep iptables
+	sudo systemctl disable --now iptables.service 2>/dev/null
+	sudo systemctl disable --now ip6tables.service 2>/dev/null
+	sudo pacman -Rns iptables
+
+	sudo rm -rf /etc/iptables
+	sudo rm -f /etc/iptables/iptables.rules
+	sudo rm -f /etc/iptables/ip6tables.rules
+
+	sudo pacman -S nftables
+	sudo systemctl enable --now nftables
+
+	sudo pacman -S gufw
+	```
+
+2. configurating firewalld 
+	```bash 
+	sudo firewall-cmd --zone=public --add-masquerade --permanent
+	sudo firewall-cmd --zone=public --query-masquerade
+	sudo firewall-cmd --reload
+	```
+
+3. opening port for service 
+	```bash
+	sudo firewall-cmd --zone=<zone> --add-port=<PORT>/<PROTOCOL> --permanent
+	sudo firewall-cmd --reload
+	```
+
+### For making window can listen request from dns 
+I dont know some how but if we change DNS listen on Settings UI it is suck, we must change by command: 
+
+turn on terminal at `Admin` and run command below:
+```bash 
+PS C:\Users\huyph> Set-DnsClientServerAddress -InterfaceAlias "Ethernet" -ServerAddresses ("192.168.1.204","::")
+PS C:\Users\huyph> Get-DnsClientServerAddress
+```
