8.1.1
IP address pools
Dynamic IP Address Server
X4000 can operate as a dynamic IP address server for PPP connections. You
can use this function by providing one or more pools of ➤➤ IP addresses.
These IP addresses can be assigned to dial-in WAN partners for the duration of
the connection.
Any host routes entered always have priority over IP addresses from the
address pools. That is, when an incoming call has been authenticated, X4000
first checks whether a host route is entered in the routing table for this caller. If
not, X4000 can assign an IP address from an address pool (if available).
If address pools have more than one IP address, you cannot specify which
WAN partner receives which address. The addresses are initially assigned in
order. If a new dial-in takes place within an interval of one hour, an attempt is
made to assign the same IP address assigned to this partner the last time.
Configuration is made in:
