Hi again,
I'm back with the progress, this is strange as the suggestion helped but NOT completely!
Some things got fixed but not all...
We're being able to ping from subnet1 to subnet2, and addresses on internet from subnet1 but we're not able to browse resources(smb...) on subnet2 nor the web-sites.
subnet2 is able to communicate to internet and with subnet1 as we're able to browse/ping printer/web-interface.
the srx is setup with default lan-configuration and static-ip on wan.
there are 2 defautl zones trust/untrust
i've set up dnat-rules and snat-rules and created some security policies.
This firewall is supposed to exchange the old one which we dont have access to and the config is build by trial/error.
Thanks in advance guys, any help is appreciated.
