Allow traffic mikrotik site to site.

L0 Member

Hi everyone. I just installed a firewall at an office. Office A is connected to office B via two site-to-site mikrotiks.
Inside office A there is a server that records the presence of office B employees.
After introducing the PA440 it stopped working..
Currently the firewall is configured like this:
Previously the router in office A was connected directly to the mikrotik and it worked via the open ports.
Now there is the PA440 between the router and the mikrotik. The router is configured in DMZ on the WAN port of the PA440.
How can I allow mikrotik traffic?
The mikrotiks were installed by another company and I am not allowed to check or change the configurations.

I'm not very practical. Please advise me the easiest solution?

Hi @AlessioS ,


It might help providing a small diagram to help visualize because I fail to understand how traffic is flowing exactly.


Are you seeing blocked or dropped packets on the PA-440 ? Is the PA configured to allow the related traffic ?


Kind regards,
