I’m working on integrating a new Palo Alto firewall into a setup, but I’m having some trouble getting the Peplink Balance router to accept traffic and make the correct routes to the correct remote VPN networks.
I’ll attach a diagram, but the basics of the system is that the PA firewall is the default gateway, installed in the route table is a static route that does a next hop IP address to the LAN IP address of the Balance 380 in our facility, that should route that traffic accordingly to remote sites, and replies come through the same path back.
The weird part is that I am able to ping any/all devices on the remote network, but I am unable to get any other traffic to pass correctly. I’ve disabled all the rules/policies on the firewall, it just seems like the traffic doesn’t make it.
Am I just going about the architecture wrong? I had an edgerouter infinity in the place of the PA before, and those static routes seemed to work okay, but I’ve tried everything I can think of and am wondering if there’s a setting I need to modify on the Balance to accept the traffic and forward it.
