FSM73xx GSM73xx GMS72xxR –Shared access to the Internet across
Multiple routing VLANs using a Prosafe Firewall
This document describes how to:
-Create multiple routing VLANs
-Obtain Internet access on multiple VLANs using one Internet gateway
The procedure described can apply to most Layer 2 and Layer 3 Switches and VPN Firewall with new
Web Interface (defined as the one with the Menus appearing horizontally on top).
Hardware differences among different models must be taken in consideration.
NOTE:
This document is not intended to illustrate how to perform full Layer3 separation, for which Access
Control Lists (ACLs) should be used.
