• Type: UDP
• Destination: 1234
B. Create a Multicast Policy object:
1. Go to: Policies > Firewalling > Main IP Rules > Add > Multicast Policy
2. Now enter::
• Name: my_multicast_policy
• Source Interface: wan
• Source Network: 192.168.10.1
• Destination Interface: core
• Destination Network: 239.192.10.0/24
• Service: my_multicast_service
3. Under Destination Translation add one entry each for the output interfaces if1, if2 and if3
and leave the IP Address fields blank since no destination address translation is required.
4. Enable the option Require IGMP
5. Click OK
The CLI for the above example is not listed since it requires the same considerations as the CLI
described for the earlier Example 4.16, "Forwarding Multicast Traffic with a SAT Multiplex IP Rule" .
Instead of an IPRule object in the CLI, a MulticastPolicy object could be used instead.
4.7.2.3. Multicast Forwarding - Address Translation Scenario
This scenario is based on the previous scenario but this time the multicast group is translated.
When the multicast streams 239.192.10.0/24 are forwarded through the if2 interface, the
multicast groups should be translated into 237.192.10.0/24.
The diagram below illustrates this situation.
