Change MAC address

On rare occasions it may be necessary to change the Ethernet hardware or MAC Address of your CyberGuard SG appliance. The MAC address is a globally unique address and is specific to a single CyberGuard SG appliance. It is set by the manufacturer and should not normally be changed. However, you may need to change it if your ISP has configured your ADSL or cable modem to only communicate with a device with a known MAC address. On SG570 and SG575, you may also change the MAC address of the DMZ port.

QoS Traffic Shaping

Traffic shaping provides a level of control over the relative performance of various types of IP traffic. The traffic shaping feature of your CyberGuard SG appliance allows you to allocate High, Medium, or Low priority to the following services: domain (tcp), domain (udp), ftp, ftp-data, http, https, imap, irc, nntp, ntp, pop3, smtp, ssh, and telnet.

This advanced feature is provided for expert users to fine tune their networks. The Auto Traffic Shaper uses a set of inbuilt traffic shaping rules to attempt to ensure low latency on interactive connections, while maintaining fast throughput on bulk transfers. The Upstream and Downstream Speed should. If you have a PPTP or PPPoE connection to the Internet, enter approximately 80 – 90% of the speed that the ISP supplied to account for protocol overheads.
