WAN 1 gateway IP address: ______.______.______.______
WAN 1 subnet mask: ______.______.______.______
WAN 2 fixed or static Internet IP address: ______.______.______.______
WAN 2 gateway IP address: ______.______.______.______
WAN 2 subnet mask: ______.______.______.______
• ISP DNS server addresses. If you were given DNS server addresses, complete the
following:
WAN 1 primary DNS server IP address: ______.______.______.______
WAN 1 secondary DNS server IP address: ______.______.______.______
WAN 2 primary DNS server IP address: ______.______.______.______
WAN 2 secondary DNS server IP address: ______.______.______.______
• Host and domain names. Some ISPs use a specific host or domain name such as
CCA7324-A or home. If you were not given host or domain names, you can use the
following examples as a guide:
- If your main email account with your ISP is aaa@yyy.com, 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, use xxx.yyy.com as the domain name.
WAN 1 ISP host name: _______________________
WAN 1 ISP domain name: _______________________
WAN 2 ISP host name: _______________________
WAN 2 ISP domain name: _______________________
• Fully qualified domain name. Some organizations use a fully qualified domain name
(FQDN) from a Dynamic DNS service provider for their IP addresses.
Dynamic DNS service provider: ______________________
WAN 1 FQDN: ______________________
WAN 2 FQDN: ______________________

Overview of the Planning Process
The areas that require planning when you use a firewall that has multiple WAN ports such as
the VPN firewall include the following:
• Inbound traffic (port forwarding, port triggering)
• Outbound traffic (protocol binding)
• Virtual private networks (VPNs)
