Multicast Forwarding - Address Translation; Forwarding Of Multicast Traffic Using The Sat Multiplex Rule - D-Link NetDefend DFL-210 User Manual

4.5.2. Multicast Forwarding using the
SAT Multiplex Rule
Example 4.8. Forwarding of Multicast Traffic using the SAT Multiplex Rule
In this example, we will create a multiplex rule in order to forward the multicast groups 239.192.10.0/24:1234 to
the interfaces if1, if2 and if3. All groups have the same sender 192.168.10.1 which is located somwhere behind
the wan interface. The multicast groups should only be forwarded to the out interfaces if clients behind those
interfaces have requested the groups using IGMP. The following steps need to be executed to configure the
actual forwarding of the multicast traffic. IGMP has to be configured seperately.
Web Interface
A. Create a custom service for multicast called multicast_service:
1. Go to Objects > Services > Add > TCP/UDP
2. Now enter:
• Name: multicast_service
• Type: UDP
• Destination: 1234
B. Create an IP rule:
1. Go to Rules > IP Rules > Add > IP Rule
2. Under General enter.
• Name: a name for the rule, eg. Multicast_Multiplex
• Action: Multiplex SAT
• Service: multicast_service
3. Under Address Filter enter:
• Source Interface: wan
• Source Network: 192.168.10.1
• Destination Interface: core
• Destination Network: 239.192.10.0/24
4. Click the Multiplex SAT tab and add the output interfaces if1, if2 and if3 one at a time. For each interface,
leave the IPAddress field blank since no destination address translation is wanted.
5. Make sure the forwarded using IGMP checkbox is set
6. Click OK
