Firewall

Selecting Firewall in the Security screen generates the “Firewall Settings” screen. Select the level of security needed for the network.

☞Note: If VPN connections need to made through the Modem, the Firewall must be set to Off. No VPN connections can be made if the Firewall setting is at Custom, High, Medium,

or Low. Also note that DMZ hosting, Port Forwarding, and Application Level Modem settings are active only when the Firewall is Off.

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.
