and I already know public IP og juniper firewall that I connect, and all hq vlan be hide firewall ,  I follow up these link to configure ( for ASA only , because juniper is under  outsource control ) http://www.petenetlive.com/KB/Article/0000710.htm

but it look like tunel is not up,  outsource confirm can ping to router  ( they and remote to server in branch site with remote desktop that I create nat policy ), but on ASA can not ping and trace route to juniper firewall ,  one error that I can find is "config implicit rule ) when I try with packet tracer,

 

please help me which path that I wrong, and how to make it up,

 

Thank you for your support

Hi;

Did you check the Perfect Forward Secrecy?  By default, Juniper firewall enable this feature.  Try turn it on at your Cisco firewall.
