Adding IP Protocol

When the type of the service is IP Protocol, an IP protocol number may be specified in the

text field. To have the service match the GRE protocol, for example, the IP protocol should be

specified as 47. A list of some defined IP protocols can be found in the appendix named "IP

Protocol Numbers".

IP protocol ranges can be used to specify multiple IP protocols for one service. An IP

protocol range is similar to the TCP and UDP port range described previously; the range 1-4,

7 will match the protocols ICMP, IGMP, GGP, IP-in-IP and CBT.

Follow these steps to add a TCP, UDP or TCP/UDP service.

Step 1. Go to Firewall and Service and choose new.

Step 2. Enter a Name for the service in the name field. This name will appear in the

service list when you add a new policy. The name can contain numbers (0-9) and upper

and lower case letters (A-Z, a-z), and the special characters - and _. No other special

characters and spaces are allowed.

Step 3. Select IP Protocol.

Step 4. Specify a comma-separated list of IP protocols.

Services can be grouped in order to simplify configuration. Consider a web server using

standard http as well as SSL encrypted http (https). Instead of having to create two separate

rules allowing both types of services through the firewall, a service group named, for instance,

Web, can be created, with the http and the https services as group members.

Follow these steps to add a group.
