10.6  PPPoE/PPTP Interfaces 
This section introduces PPPoE, PPTP, and PPPoE/PPTP interfaces and then explains the 
screens for PPPoE/PPTP interfaces.
10.6.1  PPPoE/PPTP Overview
Point-to-Point Protocol over Ethernet (PPPoE, RFC 2516) and Point-to-Point Tunneling 
Protocol (PPTP, RFC 2637) are usually used to connect two computers over phone lines or 
broadband connections.
Edit static DHCP 
table
Click this if you want the ZyWALL to assign static IP addresses to computers. 
The Static DHCP screen appears.
Figure 137   Network > Interface > Edit > Edit static DHCP table
The ZyWALL checks this table when it assigns IP addresses. If the computer’s 
MAC address is in the table, the ZyWALL assigns the corresponding IP 
address. Otherwise, the ZyWALL assigns the IP address dynamically using the 
IP Pool Start Address and Pool Size.
Note: You must click OK in the Static DHCP screen and then 
click OK in this screen to save your changes.
Ping Check
The interface can regularly ping the gateway you specified to make sure it is still 
available. You specify how often the interface pings the gateway, how long to 
wait for a response before the attempt is a failure, and how many consecutive 
failures are required before the ZyWALL stops routing to the gateway. The 
ZyWALL resumes routing to the gateway the first time the gateway 
acknowledges the ping.
Enable

Check Period
Enter the number of seconds between ping attempts.
Check Timeout
Enter the number of seconds to wait for a response before the attempt is a 
failure.
Check Fail 
Tolerance
Enter the number of consecutive failures before the ZyWALL stops routing 
through the gateway.
