SMCD3GNV4 and SMCD3GNV4E Wireless EMTA Gateway Administrator Manual 

Path: Gateway > Firewall 

 

The Gateway includes a built-in firewall whose security level can be selected using the Firewall Settings 

page. Security levels range from minimum (low security) to maximum (high security). A Custom 

Security option lets you customize security settings to suit your requirements.   

 

Maximum Security (High) 

Maximum security is the highest level of firewall security. It 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. It 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 low level 

security 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 59) 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 26).
