Adding Ip Protocol; Grouping Services - D-Link DFL-1100 User Manual

Adding other IP Protocols
When the desired type of 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>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.
Click Apply to apply the change, or click Cancel to discard the changes.

Grouping Services

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.
Step 1. Go to Firewall> Service and choose New.
Step 2. Enter a Name for the service group 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 Group.
Step 4. Specify a comma-separated list of existing services.
