Network Connections
37
Use PPPoE if your ISP uses username and password authentication to access the
Internet. Use DHCP if your ISP does not require a username and password, or your ISP
instructed you to obtain an IP address dynamically. If your ISP has given you an IP
address or address range, you must Manually Assign Settings.
For PPPoE, enter the user name and password for your ISP account. By default, your
CyberGuard SG appliance maintains the ADSL connection continuously. Alternatively
you may choose to only bring the connection up when PCs on the LAN are trying to
reach the Internet by checking the Connect on Demand box. If you are connecting on
demand, enter an Idle Disconnect Time. This is the time (in minutes) that the
CyberGuard SG appliance will wait before disconnecting when the connection is idle.
DHCP connections may require a hostname to be specified, but otherwise all settings
are assigned automatically by your ISP.
For Manually Assign Settings connections, enter the IP Address, Netmask and
optionally the Gateway and the DNS Address if provided by your ISP. Multiple DNS
addresses may be entered separated by commas.
Reboot the CyberGuard SG appliance for the new configuration to take effect.
If you are unsure of the ADSL connection method, select Auto detect ADSL connection
type and your CyberGuard SG appliance will attempt to automatically determine the
connection method.
Direct Internet
If you have a direct connection to the Internet, select this option. Typically your ISP will
have provided you with network settings (possibly a range of IP addresses), or asked you
to auto-configure using DHCP.
To use DHCP, check the DHCP Assigned check box. You may also enter one or more
DNS Server(s), however any DNS server addresses allocated by your ISP will take
precedence over these.
