Siemens 2614 Manuel D’Utilisation

From the Advanced Setup | Firewall screen, you can enable the SpeedStream 2614 firewall to block 
common hacker attacks, including IP Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf 
Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding. The firewall does not 
significantly affect system performance, so we advise leaving it enabled to protect your network users.

From the Advanced Setup screen, you can enable Virtual Server. If you configure the SpeedStream 2614 as 
a virtual server, remote users accessing services such as Web or FTP at your local site via public IP 
addresses can be automatically redirected to local servers configured with private IP addresses. Depending 
on the requested service (TCP/UDP port number), the SpeedStream 2614 redirects the external service 
request to the appropriate server located at another internal IP address.

To use the Virtual Server, the WAN interface must have a fixed IP address. Some of the more common 
TCP service ports include HTTP: 80, FTP: 21, Telnet: 23 and POP3: 110.

1. Specify the Private IP, Private Port, Type, and Public Port information. 

2. Click Enter to save the settings and continue.

You can have the system automatically enter the most common application ports:

1. Scroll to the bottom of the Advanced Setup | Virtual Server screen.

2. In the Well known services box, select the desired service.

3. Click in the box to the right of Copy to and select the line number to which the system will enter that
