There could be a few things wrong:

  • First try the SNAT Automap selection. You wouldn't want to use this in production, but whether or not it works will tell us more about the problem.

  • TCPdump on the server side VLAN of the BIG-IP. Here you want to see if any traffic is making its way to the server, and what the IPs are.

    tcpdump -lnni [server-side vlan]

The fact that you can access the pool member directly from your client machine implies that you're either on the same network, or have a route to it, and not going through the BIG-IP to get to it. This could either mean that the SNAT configuration is incorrect, or that perhaps you're not making it to the BIG-IP VIP in the first place.
