AC1750 Smart WiFi Router 2. Your IRC client composes a request message to an IRC server using a destination port number of 6667, the standard port number for an IRC server process. Your computer then sends this request message to your router. 3. Your router creates an entry in its internal session table describing this communication session between your computer and the IRC server. Your router stores the original information, performs Network Address Translation (NAT) on the source address and port, and sends this request message through the Internet to the IRC server. 4. Noting your port triggering rule and observing the destination port number of 6667, your router creates another session entry to send any incoming port 113 traffic to your computer. 5. The IRC server sends a return message to your router using the NAT-assigned source port (for example, port 33333) as the destination port and sends an "identify" message to your router with destination port 113. 6. When your router receives the incoming message to destination port 33333, it checks its session table to see if a session is active for port number 33333. Finding an active session, the router restores the original address information replaced by NAT and sends this reply message to your computer. 7. When your router receives the incoming message to destination port 113, it checks its session table and finds an active session for port 113 associated with your computer. The router replaces the message's destination IP address with your computer's IP address and forwards the message to your computer. 8. When you finish your chat session, your router eventually senses a period of inactivity in the communications. The router then removes the session information from its session table, and incoming traffic is no longer accepted on port numbers 33333 or 113. Specify Internet Port Settings 167

Your IRC client composes a request message to an IRC server using a destination port

number of 6667, the standard port number for an IRC server process. Your computer then

sends this request message to your router.

Your router creates an entry in its internal session table describing this communication

session between your computer and the IRC server. Your router stores the original

information, performs Network Address Translation (NAT) on the source address and port,

and sends this request message through the Internet to the IRC server.

Noting your port triggering rule and observing the destination port number of 6667, your

router creates another session entry to send any incoming port 113 traffic to your computer.

The IRC server sends a return message to your router using the NAT-assigned source port

(for example, port 33333) as the destination port and sends an “identify” message to your

router with destination port 113.

When your router receives the incoming message to destination port 33333, it checks its

session table to see if a session is active for port number 33333. Finding an active session,

the router restores the original address information replaced by NAT and sends this reply

message to your computer.

When your router receives the incoming message to destination port 113, it checks its

session table and finds an active session for port 113 associated with your computer. The

router replaces the message’s destination IP address with your computer’s IP address and

forwards the message to your computer.

When you finish your chat session, your router eventually senses a period of inactivity in the

communications. The router then removes the session information from its session table,

and incoming traffic is no longer accepted on port numbers 33333 or 113.
