Firewall Default DROP IGMP - how to allow?

Hi Matt,

IGMP is dropped by default by the last rule in the firewall rule set. I found no option to allow IGMP in generally. But it's possible to create a firewall rule which allows IGMP:

Source: Network or single hosts / your APs

Service: Any

Destination: IPv4 Multicast

I'm not sure if the destination object "IPv4 Multicast" is an standard object in Sophos UTM, or if I had create it. So if you need to create this object it must look like this:

Thanks Jas - perfect response, I had it close just didn't know the multicast definition.

For the record, I did need to create the network definition, just for anyone else that has the same issue.

I have implemented that rule, will see how we go.

Thanks very much for the quick response.

Cheers,

Matt
