Typically, a company maps its internal network addresses to a global external IP address and unmaps the
global IP address on incoming packets back into internal IP addresses. This helps ensure security since each
outgoing or incoming request must go through a translation process. This also offers the opportunity to qualify
or authenticate the request or match it to a previous request. NAT also conserves the number of global IP
addresses that a company needs.
Proxy Address Resolution Protocol (ARP)
Support for Proxy Address Resolution Protocol allows IP Office to respond on behalf of the IP address of a
device connected to it when receiving an ARP request.

Auto Connect

If a service is idle, that is no one is using the Internet, Auto Connect allows the IP Office to periodically connect
to a service. This is ideal for mail polling to retrieve email from an Internet Service Provider. An 'Auto Connect
Time Profile' controls the time period during which automatic calls are made, for example not at weekends or
during the middle of the night.
Firewall
IP Office integrated firewall provides packet filtering of the most common IP protocols including File Transfer
Protocol (FTP) and Internet browsing (HTTP). Each protocol passing through the firewall can be restricted/
allowed access in four different ways:
Drop
·
No sessions via this protocol will be allowed through the wall
In
·
An incoming session can "punch a hole" in the wall to allow traffic in both directions
Out
·
An outgoing session can "punch a hole" in the wall to allow traffic in both directions
Bothway
·
An incoming or outgoing sessions can "punch a hole" in the wall to allow traffic in both directions.
In cases where a protocol is not supported by default, the firewall can be customized to control packets based
on their content.
IP Office allows the configuration of as many firewalls as needed through IP Office Manager. This permits
different security regulations to be applied to individual dial-in users and data services.
Light-Weight Directory Access Protocol (LDAP)
IP Office supports LDAP directory synchronization. This allows the telephone number Directory (names and
telephone numbers) held in IP Office to be synchronized with the information on an LDAP server (limited to
5000 entries). Although targeted for interoperation with 'Windows 2000 Server Active Directory', the feature is
sufficiently configurable to interoperate with any server that supports LDAP version 2 or higher.
Remote Access Server (RAS)
IP Office provides RAS functionality allowing external users to dial in to the local area network from modems,
telephone adaptors and routers. Several of the previously described features and services can be applied to the
dial-in users to create a powerful Remote Access Server. Dial-in users can be authenticated using either PAP or
CHAP. Once authenticated the DHCP server can automatically assign the user an IP address to use while
connected to the LAN. Individual time profiles and firewalls can be applied to the user restricting what they
have access to and when they have access. For further security and accounting ease, IP Office can
automatically call a user back. This keeps the cost of the telephone call on the company telephone bill removing
the need to process individual expense claims.
Routing Information Protocol (RIP)
RIP is a distance vector protocol that allows routers to determine the shortest route to a destination network. It
does this by measuring the number of intermediary routers that need to be traversed to reach the destination
network. If more than one route exists to the same destination the shortest route is used. If a fault occurs on
the shortest route it will be remarked as being infinite and any alternative route will become the new shortest
route. This behavior can be used to add resilience into a data network. Where a customer has an existing data
