(Optional) Configuring the Aging Time of the Firewall Session Table

(Optional) Configuring the Aging Time of the Firewall Session Table

Context

The Router creates a session table for data flows of each protocol, such as TCP, UDP, and ICMP, to record the connection status of the protocol. An aging time is set for the session table. If a record in the session table does not match any packet within the aging time, the system deletes the record.

To change the aging time of protocol sessions, set the aging time of the firewall session table.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    firewall-nat session { dns | ftp | ftp-data | http | icmp | tcp | tcp-proxy | udp | sip | sip-media |  rtsp | rtsp-media | pptp | pptp-data } aging-time time-value

    The aging time of the firewall session table is set.

    By default, the aging time of each protocol is as follows:
    • DNS: 120 seconds
    • FTP: 120 seconds
    • FTP-data: 120 seconds
    • HTTP: 120 seconds
    • ICMP: 20 seconds
    • TCP: 600 seconds
    • TCP-proxy: 10 seconds
    • UDP: 120 seconds
    • SIP: 1800 seconds
    • SIP-media: 120 seconds
    • RTSP: 60 seconds
    • RTSP-media: 120 seconds
    • PPTP: 600 seconds
    • PPTP-data: 600 seconds
    NOTE:

    The default aging time is recommended.

    AR510 series do not support the sip and sip-media keywords.
