Connectivity
Nailed-Up Select this if the PPPoE/PPTP connection should always be up. Clear
this to have the ZyWALL establish the PPPoE/PPTP connection only
when there is traffic. You might use this option if a lot of traffic needs
to go through the interface or it does not cost extra to keep the
connection up all the time.
Dial-on-

only when there is traffic. You might use this option if there is little
traffic through the interface or if it costs money to keep the
connection available.

down box lists ISP accounts by name. Use Create new Object if you

have the same priority, the ZyWALL uses the one that was configured
first.
