NETGEAR UTM50-100NAS, UTM5-100NAS manual Outbound Rules Service Blocking

ProSecure Unified Threat Management (UTM) Appliance Reference Manual

•Quality of Service (QoS) priorities. Each service has its own native priority that impacts its quality of performance and tolerance for jitter or delays. You can change the QoS priority, which changes the traffic mix through the system (see “Creating Quality of Service (QoS) Profiles” on page 5-35).

Outbound Rules (Service Blocking)

The UTM allows you to block the use of certain Internet services by PCs on your network. This is called service blocking or port filtering.

Note: See “Enabling Source MAC Filtering” on page 5-42 for yet another way to block outbound traffic from selected PCs that would otherwise be allowed by the firewall.

Warning: Allowing inbound services opens security holes in your UTM. Only enable those ports that are necessary for your network.

Table 5-2 on page 5-5describes the fields that define the rules for outbound traffic and that are common to most Outbound Service screens (see Figure 5-3 on page 5-14, Figure 5-6 on page 5-17, and Figure 5-9 on page 5-20).

The steps to configure outbound rules are described in the following sections:

•“Setting LAN WAN Rules” on page 5-12

•“Setting DMZ WAN Rules” on page 5-15

•“Setting LAN DMZ Rules” on page 5-19.
