12.8 Configuring Security

To change your ZyAIR's security settings, click REMOTE MGMT, then the Security tab.
The screen appears as shown.
If an outside user attempts to probe an unsupported port on your ZyAIR, an ICMP response
packet is automatically returned. This allows the outside user to know the ZyAIR exists. Your
ZyAIR supports anti-probing, which prevents the ICMP response packet from being sent. This
keeps outsiders from discovering your ZyAIR when unsupported ports are probed.
