PLEASE HELP.. same config but not working! from PA 3050 to PA 3220

L2 Linker

Dear experts,


I am moving from PA3050 to PA3220. I did export the current configurations from the old PA3050 and imported to the new PA3220, i committed successfully, but when i migrate cables from old device to the new one i get random issue! like some zones are not reachable, like i have ping to internet and telnet and traceroute but i can't browse!, like i can't ping some destinations. WEIRD! its the SAME configuration and OS versions are the same on both devices plus, i did download and install latest content version on both devices before moving the exporting the config file.xml.


NOTE: when i move to old PA3050 all work properly!


One more thing, we have A10 (SSL Interception) connected to PA from external side and StormShield (AS core firewall).





So both old and new firewall are set to True?


I think you said you're using the copper interfaces on the PA? Do they connect directly to the A10? SFPs on another device shouldn't matter for the connection to the PA.

If you havent figured this inbox me and I can help you. 

Yes on both devices its True. 


Palo Alto Copper interfaces are connecting to the A10 device (using SFPs Fiber to Copper).

Yes, please i would appreciate if you can help with this.. but i didn't know how to inbox your from here -_-

This is to inform that this issue has been finally solved ! there was a static ARP on the core firewall interface. We put dynamic and ll worked properly. 



Thank you all.
