Description

Maximum Security (High)

Maximum security is the highest level of firewall security. This level blocks all applications including voice applications (such

as Gtalk and Skype) and P2P applications, but permits Internet browsing, email, VPN, DNS, and iTunes services.

Typical Security (Medium)

Typical security is the medium level of firewall security. This level blocks P2P applications and pings to the Gateway, while

permitting all other traffic.

Minimum Security (Low)

Minimum security is the lowest level of firewall security. It does not block applications and traffic. Select this level if you are

not familiar with firewall settings.

Custom Security

This security level is pre-configured to block all local network access from the Internet, except “trusted computers" defined

on the Managed Sites page (see page 57) and Managed Services page (see page 64). Only commonly used services, such

as Web browsing and E-mail, are permitted. If you select this option, a list of check boxes let you disable the entire firewall

or block certain traffic (see Figure 25).
