Changing the standard firewall settings
You can activate or deactivate the following functions:
◆ SPI and anti-DoS firewall protection
The router monitors incoming data traffic. If this option has been activated, the
router will only let those data packets through that have requested by applications
run by users on your local network. All other data packets will be rejected.
You can release applications for incoming traffic using Stateful Packet Inspection.
If for example you activate only FTP service, all incoming traffic will be blocked
apart from the data for FTP connections that have been initiated on the local
network.
◆ RIP error
RIP is a protocol used by routers to exchange information about their networks.
Faulty RIP packets slow down the data flow and can be provoked to paralyse a
network. If this option has been activated, the firewall will identify and reject RIP
errors.
◆ Reject Ping from WAN side
A ping command can be used to tell whether a PC can be reached via the network.
If you activate this option, all attempts to contact a computer on the local network
with a ping will be blocked.
Notification of attempted hacker attacks
You can choose to be informed by email about a possible hacker attack.
◆ Enter in the dialog boxes in When hackers attempt to enter your network, we can
alert you by e-mail.
– the email address to be used for notification about hacker attacks.
– the address of the SMTP server (email server) of your Internet Service Provider,
e. g. mailto.t-online.de.
