Using Enterprise Edge Services 25

P0910464 Issue 01 Enterprise Edge Networking Operations Guide

Enterprise Edge supports the following packet filtering features for IP:

Note: When you set filters, you must forward packets going to the RPC port (port

135 TCP or UDP) for correct Unified Manager operation.

LAN-to-LAN Fast Path Routing

Enterprise Edge provides an optional second 10/100 LAN interface. If the second

LAN interface is used, Enterprise Edge uses optimized software for high

performance routing. This includes an innovative design that speeds up the

performance for LAN-to-LAN routing by over three times the rate that is normally

achieved using traditional software architecture.

Dynamic Host Configuration Protocol (DHCP)

DHCP (Dynamic Host Configuration Protocol) is a protocol that lets network

administrators manage and automate the assignment of Internet Protocol (IP)

addresses in an organization's network. Using the Internet's set of protocols (TCP/

IP), each machine that can connect to the Internet needs a unique IP address. If an

organization sets up its computer users with a connection to the Internet, an IP

address must be assigned to each machine.

Without DHCP, the IP address must be entered manually at each computer. If

computers move to another location in another part of the network, a new IP address

must be entered. DHCP lets a network administrator supervise and distribute IP

addresses from a central point and automatically sends a new IP address if a

computer connects to a different place in the network.

You can set up Enterprise Edge to be your LAN’s DHCP server and let it assign IP

addresses to the workstations on your LAN as they need them. This is the

recommended configuration.

Packet Filter Feature Comments

Source Address the source address field of the packet to be filtered.

Source Mask the source address mask of the packet to be filtered.

Destination Address the destination address field of the packet to be filtered.

Destination Mask the destination address mask of the packet to be filtered.

Protocol the protocol type of the packet to be filtered.

Source Port the source port of the packet to be filtered. This field applies

only if protocol value is TCP or UDP.

Destination Port the destination port of the packet to be filtered. This field

applies only if protocol value is TCP or UDP.

ICMP Type the ICMP type field of the packet to be filtered. This field

applies only if protocol value is ICMP.

ICMP Code the ICMP type field of the packet to be filtered. This field

applies only if protocol value is ICMP.
