I have a problem where I am unable to ping google and it somehow seems as the firewall is missing a route back to my client. My client is inside a VLAN (172.16.87.99) and from the traffic below I can see that it correctly routes to the gateway address on port2 192.168.1.2 and that google responsd to this ip on port2. But now it is not routing back to port 8 and my VLAN. Has anybody any clue why? What am I missing?
tcpdump output:
