Configuring Firewall Settings

86 Firebox X Edge e-Series

5 In the Service Name text box, type the name for your service.

6 From the Protocol drop-down list, select TCP Port, UDP Port, or Protocol.

7 In the text box adjacent to the Protocol drop-down list, type a port number or protocol number. To

use a range of ports, type a port number in the second text box.

Note

An IP protocol number is not the same as a TCP or UDP port number. TCP is IP protocol number 6 and

UDP is IP protocol number 17. If you use an IP protocol that is not TCP or UDP, you must enter its

number. IP protocols numbers include: 47 for GRE (Generic Routing Encapsulation) and 50 for ESP

(Encapsulated Security Payload). Most settings are done with TCP or UDP ports.

8 Click Add.

Repeat steps 6-8 until you have a list of all the ports and protocols that this service uses. You can add more than one

port and more than one protocol to a custom service. More ports and protocols can make the network less secure.

Add only the ports and protocols that are necessary.

Filter traffic for an outgoing service

To limit the computers that can send incoming traffic from the external network using the service, see

“Filter incoming traffic for a custom service” on page 82. To limit what computers can send traffic from

the internal network using the service, and what computers on the external network can receive that

traffic, see “Filter outgoing traffic for a custom service” on page 82.

Services for the Optional Network

By default, the Firebox® X Edge e-Series allows all traffic that starts in the trusted network and tries to go

to the optional network, and denies all traffic that starts in the optional network and tries to go to the

trusted network.
