Static IP address
When you get an account with an ISP, you may have the option to purchase a static (permanent) IP address.
This lets you run a server, such as a Web or FTP server, because the address remains the same, all of the
time. Any type account (dial-up or broadband) can have a static IP address.
The appliance forwards any DNS lookup requests to the specified DNS server for name resolution. The
appliance supports up to three DNS servers. When you specify multiple DNS servers, they are used in
sequence. For example, after the first server is used, the next request is forwarded to the second server and
so on.
If you have a static IP address with your ISP or are using the appliance behind another security gateway
device, select Static IP and DNS for your connection type. You can specify your static IP address and the IP
addresses of the DNS servers you want to use for name resolution.
Before configuring the appliance to connect with your static IP account, gather the following information:
■
Static IP address, netmask, and default gateway addresses
Contact your ISP or IT department for this information.
■
DNS addresses
You must specify the IP address for at least one, and up to three, DNS servers. Contact your ISP or IT
department for this information. You do not need DNS IP address entries for dynamic Internet
accounts or accounts where a DHCP server assigns the IP addresses.
If you have a static IP address with PPPoE, configure the appliance for PPPoE.
See
“PPPoE”
on page 17.
Dial-up/ISDN
There are two basic types of dial-up accounts: analog and ISDN. Analog uses a modem that connects to a
regular telephone line (using an RJ-11 connector). ISDN is a digital dial-up account type that uses a special
telephone line.
On the Symantec Gateway Security 400 Series appliance, you can use a dial-up account as your primary
connection to the Internet, or as a backup to your dedicated account. In backup mode, the appliance
automatically dials the ISP if the dedicated connection fails. The appliance re-engages the dedicated
account when it is stable; usually 30 to 60 seconds.
You can configure a primary and a backup dial-up account. You can also connect or disconnect your
account manually. You may configure a backup dial-up account if your primary dedicated account fails.
First, you must connect the modem to the appliance. Then, you use the SGMI to configure the dial-up
account.
