Hi Sir,
thank you also for your advise. The moment you mentioned access list was not pointed to outside interface that made me decide to use it and it worked.
Then i removed this configs below and it still worked well
no icmp permit any outside
no icmp permit any echo-reply outside
and i added this config below
class-map global-class
match port udp range 33434 33464
class global-class
set connection decrement-ttl
