ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308
Outbound Rules (Service Blocking)
The VPN firewall allows you to block the use of certain Internet services by computers on
your network. This is called service blocking or port filtering.
Note: See Enable Source MAC Filtering on page 186 for yet another way
to block outbound traffic from selected computers that would
otherwise be allowed by the firewall.
The following table describes the fields that define the rules for outbound traffic and that are
common to most Outbound Service screens (see Figure 74 on
page 143, Figure 80 on
page 150, and Figure 86 on p
age 156).
The steps to configure outbound rules are
described in the following sections:
• Configure LAN WAN Rules
• Configure DMZ WAN Rules
• Configure LAN DMZ Rules
