More specific details would be needed about your setup.

Pinging is yet another type of traffic (ICMP, usually).  It isn't
something that's going to be proxied like Squid proxies HTTP, FTP, and
few others.  Start by looking at your firewall rules that deal with
ICMP, and your generic overall default rules.
