It needs to be a server because the traffic is incoming to the firewall.
This is easier to understand if you imagine something on the linux
machine and you wanted to accept the traffic for it.

Apologies for it not working. I see that the PROTO is 2, which is IGMP,
so probably the connection tracker does not mark it as a connection.
Try this instead:

  server anystateless rest drop src

Note that you need to provide an additional name after anystateless.
It doesn't really matter what it is.
