Configuration of Multiple Public IPs in DeMilitarized Zone (DMZ) on RV042, RV042G and RV082 VPN Routers

Objective

The Demilitarized Zone (DMZ) is an internal network of an organization, which is made available to an untrusted network. As per security, the DMZ falls between trusted and untrusted networks. Maintenance of the DMZ helps to improve security ofto an organization's internal network. When an Access Control List (ACL) is bound to an interface, its Access Control Element (ACE) rules are applied to packets that arrive at that interface. Packets that do not match any of the ACEs in the Access Control List are matched to a default rule whose action is to drop unmatched packets.

The objective of this document is to show you how to configure the DMZ port to allow Multiple Public IP addresses and define the Access Control List (ACL) for IPs on the router device.
