Enable Firewall Protection

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.

Enable Virtual Server

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.
