I tried a simple multicast test in two Sophos XG 85 firewalls by following this knowledge base article: https://community.sophos.com/kb/en-us/123291/
After following exactly everything from this article, still there was no success in forwarding multicast traffic since the packets were being dropped in the first firewall.
The test was done by sending packets via iPerf. Should there be any other equipment to specify the multicast group? Or just following the configuration in this article is enough? Any help regarding this matter will be very much appreciated. Thank you.
Here is a snapshot of the packet capture:
