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 SE680 WiMAX 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 Inter-
net, as attacks and avert them (hacker defence). Your device’s firewall is enabled by
default.
If you still want to disable the firewall:
Open the
Advanced Settings
tab and on the
Internet
menu select
Firewall
.
Disable the firewall.
Connect on demand
The Internet connection is only established if an application, e.g. an Internet
browser or an e-mail program, requests it.
We urgently recommend that you leave the firewall of your SE680
WiMAX enabled, otherwise your network will no longer be protected
against hacker attacks from the Internet.
i
This function is not available in
Bridge
operating mode, see "Configuring
Internet access" on page 25.
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 29.
