cidre firewall deny ir kp --firewall ufw

• Blocks Iran (IR), and North Korea (KP) in UFW.
• Requires ufw installed (sudo apt install ufw).

# iptables is better suited for large CIDR inputs
cidre firewall deny ru ir kp --firewall iptables

cidre cidr pull --proxy PROXY	Proxies connection to RIRs. Optional.
cidre cidr pull --cidr-store PATH	Specifies CIDRs' custom storage directory. Default: ./output/cidr

cidr count

Command	Description
cidre cidr count	Counts amount of IPs per country
cidre cidr count US CN	Counts amount of IPs by country code (ISO 3166-1 alpha-2 code)

firewall allow|deny|reject

Command	Description
cidre firewall allow	Apply allow rule to specified firewall
cidre firewall deny	Apply deny rule to specified firewall
cidre firewall reject	Apply reject rule to specified firewall
cidre firewall reject --firewall ufw	Firewall to apply rules. Options: ufw, iptables. Default: ufw
cidre firewall reject --cidr-store PATH	Specifies CIDRs' custom storage directory. Default: ./output/cidr

⚠️ NOTE: iptables firewall DO NOT persist rules by default

To ensure iptables and IPSet rules persist after a reboot, follow these steps:

# Save rules based on the firewall method:
# - For iptables + IPSet:
sudo ipset save > /etc/ipset.rules
sudo iptables-save > /etc/iptables/rules.v4
sudo ip6tables-save > /etc/iptables/rules.v6

# Restore firewall rules on boot:
# - For iptables + IPSet:
sudo bash -c 'echo "ipset restore < /etc/ipset.rules" >> /etc/rc.local'
sudo chmod +x /etc/rc.local

# Reboot and verify:
sudo reboot
sudo ipset list
sudo iptables -L -v -n
