You don’t write anything about your hardware – but whatever it is, you’ll need to configure some kind of “stateful” ICMP filtering (quotation marks are there because ICMP is a stateless protocol :o ))

Just an idea how it can work:

vlan10: allow incoming and block outgoing echo requests;
block incoming and allow outgoing echo replies;

vlan20: probably, allow all echo requests/replies
