Adding new services
Service, short for network service, means a service that is available on the network, e.g. file sharing, remote
console access, or web browsing.
Services are most often described by what protocol and port they use.
Creating a new Internet service based on the default HTTP
In this example, it is assumed that there is a web server running on a computer, and the web server is
configured to use a non-standard web port.
Normally a web server would serve TCP/IP port 80, but in this example it has been configured to serve port
8000. To enable connections to this server from the workstations you will have to create a new service. The
standard HTTP service does not work here because we are not using the standard HTTP port any more. This
new service is
HTTP port 8000
and it is based on the default
HTTP
service.
1. Select the subdomain for which you want to create the new service in the Policy domains tab.
2. Go to the Settings tab and open the Firewall services page.
This page contains the Firewall services table.
3. Click the Add button to start the Firewall services wizard.
4. Enter a service name:
a) Define a unique name for the service in the Service name field; you cannot have two services with
the same name.
For example,
HTTP port 8000
.
b) Enter a descriptive comment for the service in the Service comment field.
The comment will be displayed on the Firewall services table.
5. Select an IP protocol number:
a) Select a protocol number for this service from the Protocol drop-down list.
It contains the most commonly used protocols (TCP, UDP, ICMP). If your service uses any other
protocol, refer to the table below and enter the respective number.
In this example, select TCP (6) from the IP-protocol number: drop-down list.
