Hi,
I configured port redirection with outside interface as below and allow tcp 4433 on outside interface.
nat (inside,outside) source static <inside-serv> interface service tcp_4433 tcp_4433
I could see packets are arriving on my outside interface with the port 4433 but NO response from internal server to outside. when I did the packet tracer both from outside to inside, i could see that it hits the correct NAT rule. But need to figure out why it still not working (no response from server to client). Appreciate it if someone can shed some light on this issue. thanks.

After NAT do you have ACL to allow in traffic example :
access-list inbound permit tcp any object <inside-serv> eq tcp_4433

Hello
I would agree with @balaji.bandi it possible due to acl restriction and applying that acl to the outside interface:
access-list 100 extended permit tcp any object <xxxx> eq 4433
access-group 100 in interface outside
