Connectivity
Nailed-Up Select this if the PPPoE/PPTP connection should always be up. Clear this to have the

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-Demand Select this to have the ISG50 establish the PPPoE/PPTP connection 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.
