Setting Up Dns Servers; Enabling Or Disabling The Firewall - Gigaset SX682 WiMAX User Manual

Advanced Settings
Connect on demand
The Internet connection is only established if an application, e.g. an Internet
browser or an e-mail program, requests it.
PPPoE pass-through
If you activate the PPPoE pass-through function, a PC in the network can connect to the
Internet via its own connection ID. The router puts this connection through.

Setting up DNS servers

DNS (Domain Name System) is a decentralised database on the Internet which allocates
clearly understandable Internet names (domains) to the actual addresses of PCs and
services (e.g. IP addresses). The DNS servers required for access to this database are nor-
mally provided by your provider and do not have to be set up specially. But if necessary
you can change them here.
ì
Open the Advanced Settings tab and on the Internet menu select DNS Servers.
ì
Activate the Use custom DNS servers function and enter the IP addresses for your
Preferred DNS server and the Alternate DNS server.

Enabling or disabling the firewall

Your Gigaset SX682 WiMAX comes with an integrated firewall, which protects your
device and network against unauthorised access from the Internet. If the firewall is ena-
bled, your device can identify certain events, e.g. suspicious incoming data packets
from the Internet, as attacks and avert them (hacker defence). Your device's firewall is
enabled by default.
We urgently recommend that you leave the firewall of your Gigaset
W
SX682 WiMAX enabled, otherwise your network will no longer be pro-
tected against hacker attacks from the Internet.
If you still want to disable the firewall:
ì
Open the Advanced Settings tab and on the Internet menu select Firewall.
ì
Disable the firewall.
This function is not available in Bridge operating mode, see "Configuring
Internet access" on page 35.
i
PCs in your network should be protected by a separate firewall. You can
set up protection against DoS (Denial of Service) attacks in Bridge mode
via the local network configuration, see "LAN configuration" on page 39.
