ISP DNS Server Addresses:
If you were given DNS server addresses, fill in the following:
Primary DNS Server IP Address:
______.______.______.______
Secondary DNS Server IP Address: ______.______.______.______
•
Host and Domain Names:
Some ISPs use a specific host or domain name like
CCA7324-A
or
home
. If you have not been given host or domain names, you can use the following
examples as a guide:
–
If your main e-mail account with your ISP is [email protected], then use
aaa
as your host
name. Your ISP might call this your account, user, host, computer, or system name.
–
If your ISP’s mail server is mail.xxx.yyy.com, then use
xxx.yyy.com
as the domain name.

Overview of the Planning Process
The areas that require planning when using a firewall that has dual WAN ports such as the UTM
include the following:
•
Inbound traffic (port forwarding, port triggering)
•
Outbound traffic (protocol binding)
•
Virtual private networks (VPNs)
The two WAN ports can be configured on a mutually-exclusive basis to either:
•
auto-rollover for increased reliability, or
•
load balance for outgoing traffic.
