Gateway in other VLAN pingable

I have firewalled off a VLAN behind an MX65 and have create a FW rule to block ALL traffic from that VLAN to the other 3.

I cannot ping a host in the other networks. However, I can ping all the default gateways from those networks. Is that normal behaviour ?

Kind of a big deal

Yes that is normal, however I wish by default it would also block pings. I believe you have to create a specific ACL to also block ICMP, based on these other threads.
