Connection State
• Advise, drop invalid connections
• Firewall should proceed only new packets, it is recommended to exclude other types of states
• Filter rules have the “connection state” matcher for this purpose

NAT Chains
• To achieve these scenarios you have to order your NAT rules in appropriate chains: dstnat or srcnat
• NAT rules work on IF-THEN principle
