Chapter 41 Sa Monitor; Introduction; Using Sa Monitor; Figure 41-1 Menu 27.2: Sa Monitor - ZyXEL Communications ZyWall 10W User Manual

This chapter teaches you how to manage your SAs by using the SA Monitor in SMT menu 27.2.

41.1 Introduction

A Security Association (SA) is the group of security settings related to a specific VPN tunnel. This menu
(shown next) displays active VPN connections.
When there is outbound traffic but no inbound traffic, the SA times out
automatically after two minutes. A tunnel with no outbound or inbound traffic is
"idle" and does not timeout until the SA lifetime period expires. See the web
configurator parts of this User's Guide on keep alive to have the ZyWALL
renegotiate an IPSec SA when the SA lifetime expires, even if there is no traffic.

41.2 Using SA Monitor

1. Use the Refresh function to display active VPN connections.
2. Use the Disconnect function to cut off active connections.
Type 2 in Menu 27 - VPN/IPSec Setup, and then press [ENTER] to go to Menu 27.2 - SA Monitor.
