4.5.10 Firewall
Overview The Overview page summarizes the overall security policy configured on your
SpeedTouch™.
Configure The Configure page allows you to select the security level of the SpeedTouch™.
Select one of following security levels:
Block All
: to protect your network from all attempts of incoming (from
untrusted site) connection requests and to perform checks on outgoing (from
trusted site) connections. This level is meant to prevent incoming malicious
traffic.
Standard
: to protect your network from all incoming (from untrusted site)
connection requests while permitting safe outgoing connections. This is the
default.
Disabled : to allow all incoming and outgoing traffic. This does not mean the
complete SpeedTouch™ firewall is disabled. It means all traffic coming in on one
interface and going out on another is allowed, but access to the embedded
services of the SpeedTouch™ (as telnet, web interface,...) is only allowed for
clients residing on the LAN side, so the SpeedTouch™ itself stays protected.
High
:
Use this Security Level to block all outgoing connections except well known
applications (DNS, HTTP, HTTPS, FTP, TELNET, IMAP, POP) and block all
incoming connections. Game & Application sharing is not allowed by the
firewall.
