Network Firewall Simulator

Firewall LAN (andar ke network) aur Internet (bahar) ke beech ek checkpoint hai. Har packet firewall se guzarta hai, jo apni rule list upar se neeche check karta hai — pehli matching rule packet ka fate (Allow ya Deny) decide karti hai. Koi rule match na ho to default Deny lagta hai. Stateful mode on ho to LAN ka bheja hua outbound request wapis aata hua response automatically allow ho jata hai, chahe koi inbound rule na ho.

Off kar ke dekhein — pure "static packet filter" ban jayega, tab bina explicit inbound rule ke koi bhi return traffic block ho jayega.
