Hi
From a short look into your config this is my assumption;
your security policies did not honor the fact, that the SRX has a specific sequence of first flow evaluation namely
Screen
Destination NAT or Static Nat
Routing
Policy Evaluation
Source NAT
...
so for the policies you need to mention the TRANSLATED address for the detination and the UNTRANSLATED for the source.
Pls have a check on that, and either say No or confirm my assumption
regards
