If ping works but nothing else, it usually means other traffic is being denied by your APCL/URLF layer. Ping is not an application (and need only match a rule in the Network/Firewall policy layer) but practically everything else including DNS is. Click the Matched Rules tab on your log card.
Beyond that run fw ctl zdebug drop and try to pass some traffic. If you don't see a drop in that output it is a routing (or possibly NAT) issue of some kind.
