ZyWALL USG 50 User’s Guide

• Authentication Type - Select an authentication protocol for outgoing calls. 

Options are:

• CHAP/PAP - Your ZyWALL accepts either CHAP or PAP when requested by 

the remote node. 

• CHAP - Your ZyWALL accepts CHAP only. 
• PAP - Your ZyWALL accepts PAP only. 
• MSCHAP - Your ZyWALL accepts MSCHAP only.
• MSCHAP-V2 - Your ZyWALL accepts MSCHAP-V2 only.

• Type the User Name given to you by your ISP. You can use alphanumeric and -

_@$./ characters, and it can be up to 31 characters long. 

• Type the Password associated with the user name. Use up to 64 ASCII 

characters except the [] and ?. This field can be blank. Re-type your password in 

the next field to confirm it.

• 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. 

• 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. 

• 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.
