60 Chapter 2 Configuring servers
Use the Remote User IP Address Pool window to select a method for users to
obtain IP addresses to access the private network. The VPN Router services these
addresses and they are available to remote users on demand. You can choose IP
addresses assigned from one of the following:
• external Dynamic Host Configuration Protocol (DHCP) pool
• internal address pool
A DHCP server on the private LAN segment dynamically assigns IP addresses on
behalf of remote users. You must have an existing DHCP server to choose this
option. The DHCP server is contacted by a broadcast or unicast (depending on the
option selected) DHCP request through the network adapter associated with the
management IP address.
The internal DHCP server option also provides the following:
• A cache of prenegotiated DHCP addresses so that the client does not wait to
acquire an address at logon.
• All DHCP controls (such as cache size, immediate release, blackout time,
blackout override) can fine tune the behavior of the DHCP client.
• Named pools are supported. The pool name from the user/group profile is
used to select which of the internal DHCP server pools a local address comes
from.
• A default pool can provide addresses when the preferred pool is exhausted or
unavailable. The default fail over control enables or disables the default pool.
To configure a DHCP address pool:
1 Select Servers > User IP address .
2 Click DHCP.
3 Click Any External DHCP Server to allow any available external DHCP
server to provide the requested IP addresses. Any External DHCP Server is
the default selection.
4 Click Internal DHCP Server to allow a block of addresses. These addresses
must also be specified in the user’s group profile.
5 Click Specified DHCP Server to allow a specified DHCP server only to
provide IP addresses. Indicate the IP addresses of the servers that provide
DHCP service, including Primary, Secondary, and Tertiary. A status field
