Step 5 – Assign an Ethernet Port to be a member of the Public VLAN
In the example below, we are setting the first Ethernet port as a member of VLAN 100 and setting it to “edgeport” mode to allow this port to come up immediately. This port should be plugged into your Internet connection. Make sure your workstation is not plugged into this port and remember to click the “Apply” button. Also, it is probably a good idea after making this change to click the “Save” button to save the configuration in nonvolatile memory.
Step 6 – Using the Firewall Wizard to Setup Internet Connection Sharing (NAPT)
We will use the Firewall Wizard to setup the “Security Zones” on the router. You can also setup some basic port forwarding using this wizard. Note: You only want to use this wizard for the initial configuration. All future firewall settings should be added using the “Security Zones” link.
