*Important: To complete the step of allowing remote users to FTP into the V3, you must go to the V3’s Advanced Setup page, click the Misc. Config. button, and do the following: Enable FTP Server in the dropdown list and uncheck the box “Disable WAN side FTP access.” FTP must be enabled in both places for this feature to work.
Once you’ve made your selections, click Save Changes and Write Settings to Flash and Reboot.
4.2Creating Inbound/Outbound Policies
The V3 offers ways to tailor, or restrict, incoming and outgoing Internet traffic to increase security. Your V3 comes with three inbound/outbound policies preconfigured for VoIP: 1) SIP Port 5060; 2) RTP Media Base 5000; 3) TFTP Port 60.
To create additional policies, from the main Firewall page, click the Inbound Policy or Outbound Policy link, depending on what you want to do.
Tip: When setting up policies, it may help to think of inbound and outbound policies as mirror images of each other. In each case, the source and destination IP addresses, subnet masks, and ports are reversed. That is, for an inbound policy, the source address appears on the WAN side, and the destination appears on the LAN side; for an outbound policy, the source is on the LAN side and the destination is on the WAN side.
