Add in linux input tcp state new tcp 443 accept

Here is the updated Linux iptables rule:

iptables -A INPUT -p tcp --dport 443 -m state --state NEW -j ACCEPT

Let me break it down:

• iptables: The command to manipulate the Linux firewall.
• -A INPUT: Append a new rule to the INPUT chain (which handles incoming traffic).
• -p tcp: Specify that we're only interested in TCP traffic.
• --dport 443: Specify that we're only interested in traffic destined for port 443 (HTTPS).
• -m state: Use the state module to examine the state of the connection.
• --state NEW: Only allow new connections (i.e., not established or related connections).
• -j ACCEPT: Jump to the ACCEPT target, which allows the traffic to pass through.

This rule allows new incoming TCP connections on port 443 (HTTPS) to be accepted.
