Creating a Network Service Alias
A network service alias defines a TCP, UDP or IP protocol and a list or range of ports supported by that service.

WebUI.
2. Click Add to create a new alias.
3. Enter a name for the alias in the Service Name field.
4. In the Protocol section, select either TCP or UDP, or select Protocol and enter the IP protocol number of the
protocol for which you want to create an alias.
5. In the Port Type section, specify whether you want to define the port by a contiguous range of ports, or by a list
of non-contiguous port numbers.
l If you selected Range, enter the starting and ending port numbers in the Starting Port and End Port fields.
l If you selected list, enter a comma-separated list of port numbers.
6. To limit the service alias to a specific application, click the Application Level Gateway (ALG) drop-down list

l dhcp: Service is DHCP
l dns: Service is DNS
l ftp: Service is FTP
l h323: Service is H323
