Internet Access: Pptp - ZyXEL Communications ZyWall USG20-VPN User Manual

• 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 USG 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. If you do not configure a DNS server,
you must know the IP address of a machine in order to access it.

2.1.4 Internet Access: PPTP

Note: Enter the Internet access information exactly as given to you by your ISP.
