To enable the appropriate Attack Checks for your environment:
1. Select Security > Firewall from the main/submenu.
2. Click the Attack Checks tab. The Attack Checks screen is displayed.
3. Check the boxes for the Attack Checks you wish to monitor. The various types of attack
checks are listed and defined below.
4. Click Apply to save your settings.
The various types of attack checks listed on the Attack Checks screen are:
• WAN Security Checks
– Respond To Ping On Internet Ports. By default, the VPN firewall responds to an ICMP
Echo (ping) packet coming from the Internet or WAN side. Responding to a ping can be a
useful diagnostic tool when there are connectivity problems. If the ping option is enabled,
you can allow either any IP address or a specific IP address only to respond to a ping. You
can disable the ping option to prevent hackers from easily discovering the VPN firewall
via a ping.
– Enable Stealth Mode. In stealth mode, the VPN firewall will not respond to port scans
from the WAN, thus making it less susceptible to discovery and attacks.
