Description of the illustration ''%s''acs

This figure shows firewall security implemented on the ACSLS server-side (CSI) only. The figure shows the Client and Server sides, separated by a firewall.

The Client side includes SSI, which selects the source port and can be queried by the CSI on the Server side, which includes three static ports:

1 - Designated/fixed.
2 - TCP 111
3 - UDP 111

In network failure instances, the CSI can query the SSI for the registered port.

This configuration is described in more detail in surrounding text.
