Network Setup
56
By default, Dialout/ISDN connections are treated as “always on” and is kept up
continuously. Alternatively, you may choose to only bring the connection up when PCs
on the LAN, DMZ or Guest network (via a VPN tunnel) are trying to reach the Internet.
For instructions, refer to the section entitled Dial on Demand further on in this chapter.
Port settings
If necessary, you may set the CyberGuard SG appliance’s serial port Baud rate and
Flow Control. This is not generally necessary.
Static addresses
The majority of ISPs dynamically assign an IP address to your connection when you
dialin. However some ISPs use pre-assigned static addresses. If your ISP has given
you a static IP address, click the Static Addresses tab and enter it in My Static IP
Address and enter the address of the ISP gateway in ISP Gateway IP Address.
Aliases
See the section entitled Aliases under Direct Connection.
Connection (dial on demand)
See the section entitled Connection (dial on demand) under ADSL.
Dialin
A remote user may dial directly to a modem connected to CyberGuard SG appliance’s
serial port. Once connected and authenticated, the user has access to network
resources as if they were a local user on the LAN. This may be useful for remote
administration of your CyberGuard SG appliance, or for telecommuting.
Dialin setup
Select Dialin from the Change Type pull down menu for the interface that connects to
the dialup modem to answer incoming calls.
