Firepower 1010 doesn't forward data over port 1/5 after successful upgrade from 7.2.5 to 7.2.6. It does see MAC address of a directly connected router but can't PING it. It can PING its own IP address on the port 1/5 though. It seems it can only IP communicate over its Outside port, It talks to Internet, It is able to open IPSEC routed tunnels. However, it can't IP communicate downstream.
Any ideas on this, please?
