23.3.3 IP Pools
The IP Pools menu displays a list of all IP pools for PPTP connections.
Your device can operate as a dynamic IP address server for PPTP connections. You can
use this function by providing one or more pools of IP addresses. These IP addresses can
be assigned to dialling-in connection partners for the duration of the connection.
Any host routes entered always have priority over IP addresses from the address pools.
This means if an incoming call has been authenticated, your device first checks whether a
host route is entered in the routing table for this caller. If not, your device can allocate an IP
address from an address pool (if available). If address pools have more than one IP ad-
dress, you cannot specify which connection partner receives which address. The ad-
dresses are initially assigned in order. If a new dial-in takes place within an interval of one
hour, an attempt is made to allocate the same IP address assigned to this partner the last
time.
Choose theAdd button to set up new IP pools.
