    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
