Chapter 4 Installation Setup Wizard
• Select Nailed-Up if you do not want the connection to time out. Otherwise,
type the Idle Timeout in seconds that elapses before the router automatically
disconnects from the PPTP server.
4.1.5.1 PPTP Configuration
• Base Interface: This identifies the Ethernet interface you configure to connect
with a modem or router.
• Type a Base IP Address (static) assigned to you by your ISP.
• Type the IP Subnet Mask assigned to you by your ISP (if given).
• Server IP: Type the IP address of the PPTP server.
• Type a Connection ID or connection name. It must follow the "c:id" and
"n:name" format. For example, C:12 or N:My ISP. This field is optional and
depends on the requirements of your broadband modem or router. You can use
alphanumeric and -_: characters, and it can be up to 31 characters long.
4.1.5.2 WAN IP Address Assignments
• First WAN Interface: This is the connection type on the interface you are
configuring to connect with your ISP.
• Zone This is the security zone to which this interface and Internet connection
will belong.
• IP Address: Enter your (static) public IP address. Auto displays if you selected
Auto as the IP Address Assignment in the previous screen.
• First / Second DNS Server: These fields display if you selected static IP
address assignment. The Domain Name System (DNS) maps a domain name to
an IP address and vice versa. Enter a DNS server's IP address(es). The DNS
server is extremely important because without it, you must know the IP address
of a computer before you can access it. The ZyWALL uses these (in the order
you specify here) to resolve domain names for VPN, DDNS and the time server.
Leave the field as 0.0.0.0 if you do not want to configure DNS servers.
