4.2 Creating 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.
