•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 ISG50 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.
