It’s not about firewall.
But use sysctl (in terminal) to stop replying to ping:

sysctl -w net.ipv4.icmp_echo_ignore_all=1

To turn replying back:
sysctl -w net.ipv4.icmp_echo_ignore_all=0

For a solution with the firewall itself look at this post (solution 2),
you need to use the sysconfig editor in yast.

It should still work in newer versions (but I did not test it).
