They are used to provide correct NAT traversal for these protocols. Specifications Packages required: system License required: level1 Home menu level: /ip firewall connection, /ip firewall service-port Standards and Technologies: IP Hardware usage: Increases with connections count Related Documents • IP Addresses and ARP • Routes, Equal Cost Multipath Routing, Policy Routing • Network Address Translation Notes Connection tracking must be enabled in order to use NAT.

Connection Tracking Home menu level: /ip firewall connection Description Using Connection Tracking, you can observe connections passing through the router. Connection Timeouts Here comes a list of connection timeouts: • TCP SYN sent - (first stage in establishing a connection) = 2min • TCP SYN recvd - (second stage in establishing a connection) = 60sec • Established TCP connections - (third stage) = 5 days • TCP FIN wait - (connection termination) = 2min • TCP TIME wait - (connection termination) = 2min • TCP CLOSE - (remote party sends RTS) = 10sec • TCP CLOSE wait - (sent RTS) = 60sec • TCP LAST ACK - (received ACK) = 30sec • TCP Listen - (ftp server waiting for client to establish data connection) = 2min • UDP timeout - 30sec • UDP with reply timeout - (remote party has responded) = 180sec • ICMP timeout - 30sec • All other - 10min Property Description dst-address (read-only: IP address:port) - the destination address and port the connection is established to src-address (read-only: IP address:port) - the source address and port the connection is established from protocol (read-only: text) - IP protocol name or number tcp-state (read-only: text) - the state of TCP connection timeout (read-only: time) - the amount of time until the connection will be timed out reply-src-address (read-only: IP address:port) - the source address and port the reply connection is established from reply-dst-address (read-only: IP address:port) - the destination address and port the reply connection is established to assured (read-only: true | false) - shows whether the connection is assured icmp-id (read-only: integer) - contains the ICMP ID. Each ICMP packet gets an ID set to it when it is sent, and when the receiver gets the ICMP message, it sets the same ID within the new ICMP message so that the sender will recognize the reply and will be able to connect it with the Page 247 of 568 Copyright 1999-2005, MikroTik.
