2.4 Major Features

 Address Sharing and Management

 Packet Filtering

 Defense against Denial of Service Attacks

 Application Content Filtering

 Log and Alert

 Remote Access

2.4.1.1 Address Sharing and Management

The OfficeConnect Gigabit VPN Firewall provides NAT to share a single high-

speed Internet connection and to save the cost of multiple connections required

for the hosts on the LAN segments connected to the OfficeConnect Gigabit VPN

Firewall. This feature conceals network address and prevents them from

becoming public. It maps unregistered IP addresses of hosts connected to the

LAN with valid ones for Internet access. The OfficeConnect Gigabit VPN Firewall

also provides reverse NAT capability, which enables SOHO users to host

various services such as e-mail servers, web servers, etc. The NAT rules drive

the translation mechanism at the NAT router.

2.4.1.1 ACL (Access Control List)

ACL rule is one of the basic building blocks for network security. Firewall

monitors each individual packet, decodes the header information of inbound and

outbound traffic and then either blocks the packet from passing or allows it to

pass based on the contents of the source address, destination address, source

port, destination port, protocol and other criterion, e.g. application filter,

Schedules, defined in the ACL rules.

ACL is a very appropriate measure for providing isolation of one subnet from

another. It can be used as the first line of defense in the network to block

inbound packets of specific types from ever reaching the protected network.

The OfficeConnect Gigabit VPN Firewall’s ACL methodology supports:

 Filtering based on destination and source IP address, port number and

protocol

 Filter Rule priorities

 Time based filters
