Communications problems between servers

ok, I see

but, what we cannot understand is why the F5 don´t send the connection from server C to server A; then we have the problem with the asymetric traffic, I see, but what about the other situation?

Thanks for you help !!!!

Here you have the tcpdump -i 0.0 -nn host 192.168.1.1 or host 192.168.1.2 or host 192.168.1.5
