Working with Service Objects

Note: This topic applies to the Inverness Release.

A service object is made of one or more named IP protocols or TCP / UDP ports and port ranges, or a combination of all. For example, the HTTP version of the Smoothwall administration user interface uses TCP port 81, while the HTTPS version uses TCP port 441; you can either create a service object for each individual instance, or have one service object containing both port numbers. Furthermore, you can combine multiple service objects into a service object group.

You can create and edit service objects for use throughout the Smoothwall firewall configuration. Where allowed, using service objects significantly reduces the amount of time taken to configure various aspects of your firewall. For example, if multiple firewall rules are required for RADIUS traffic, you can reduce duplication by creating a service object containing the port numbers used by RADIUS which is used by multiple rules, rather than having duplicate rules for the same port number, which is further duplicated by the number of rules required.

A number of default service objects and service object groups are made available for use in the Network > Settings > Service object manager page.

You can choose to either:

Create new service objects in the Network > Settings > Service object manager page

Add new service objects "as you go" while adding firewall-related rules:

 

Note: If your Smoothwall is part of a centrally managed solution (see Setting up a Centrally Managed System), it should be noted that any service objects or service object groups you create on the parent node are replicated to the child nodes in addition to their own service object configuration. These are prefixed with Replicated: in the relevant user interface pages.
