So I have had the same setup for quite a while, nothing has changed other than new firmware..... Two routers in OSPF config. When I try and ping from my desktop computer to network switches on the other router it just times out. But on that router if I just disable my drop invalid packets rule, the pings work just fine. Once again nothing has changed so why is it acting like this now?
My switches are on subnet 10.0.169./24 now I can ping servers on that same subnet without having to disable the firewall rule for drop invalid packets. The issue is only with my network switches.
