The routing table contains the network destinations syslog-ng Store Box (SSB) can reach. You have to make sure that the local services of SSB (including connections made to the backup and archive servers, the syslog server, and the SMTP server) are routed properly.

You can add multiple addresses along with their respective gateways.

 Caution:

Complete the following procedure only if the management interface is configured, otherwise the data sent by SSB will be lost. For details on configuring the management interface, see Configuring the management interface.

To configure the routing table

  1. To add a new routing entry, navigate to Basic Settings > Network > Interfaces and in the Routing table field, click .

    Figure 14: Basic Settings > Network > Interfaces > Routing

  2. Enter the IP address of the remote server into the Address (IPv4 / IPv6) field.

  3. Enter the related netmask /prefix into the Netmask (IPv4) / Prefix (IPv6) field.

  4. Enter the IP address of the gateway used on that subnetwork into the Gateway (IPv4 / IPv6 field.

    NOTE: Do not use IP addresses that fall into the following ranges:

    • IPv4 addresses

      • 1.2.0.0/16 (reserved for communication between SSB cluster nodes)

      • 127.0.0.0/8 (localhost IP addresses)

    • IPv6 addresses

      • ::1/128 (loopback address)
      • fe80::/10 (link-local addresses)

  5. If you want to reply on the same interface where a packet came in, select Reply on same interface. This instructs SSB to disregard connected networks other than the network of the incoming packet's interface when routing reply packets.
