Chapter 6 Configuring Security Settings
Firewall
Selecting Firewall in the Security screen generates the “Firewall Settings” screen. Select the level of security needed for the network.
High
If High is selected in the “Firewall Security Level” screen, the services listed at the bot- tom of the screen (HTTP, DNS, FTP, IMAPv3, SMTP, POP3, NNTP, IPSEC IKE, IPSEC ESP, HTTPS, and IMAP) are the only ones allowed to pass through the firewall. All other services will be blocked. None of these settings can be changed from here.
