Setting Up Dns Servers; Enabling Or Disabling The Firewall - Cisco BWX360 WiMAX User Manual

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 allo-
cates 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 normally provided by your provider and do not have to be set up specially. But if
necessary you can change them here.
Open the Advanced Settings tab and on the Internet menu select DNS Servers.
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 Cisco BWX360 WiMAX Outdoor Modem comes with an integrated firewall, which
protects your device and network against unauthorised access from the Internet. If the
firewall is enabled, 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
Cisco BWX360 WiMAX Outdoor Modem enabled, otherwise your net-
work will no longer be protected against hacker attacks from the Internet.
If you still want to disable the firewall:
Open the Advanced Settings tab and on the Internet menu select Firewall.
Disable the firewall.
This function is not available in Bridge operating mode, see "Configuring
Internet access" on page 26.
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 30.
