4.2 Creating Inbound/Outbound

Policies

The X5v offers ways to tailor, or restrict, incoming and outgoing

Internet traffic to increase security. Your X5v 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.

Inbound Policies

Inbound firewall policies allow you to filter the traffic that arrives

over the Internet—from the WAN side to the X5v LAN side—

based on rules that you set up.
