You indicated earlier that you were testing curl with https. So then if you do this from the BIG-IP shell, you see a good HTTP response?

curl http://172.17.31.254:32255/#/sessions

If you do, this request would be coming from the self-IP (.18). Is the monitor showing good for the 32255 pool member? I'm assuming here that you're only using a tcp half-open monitor, which just checks to see if the server returns an ACK. So then if you switch to a full tcp monitor, does that still show green? And you have no rules on the server to block traffic from floating .16?

If you tcpdump on both on both BIG-IPs, do you see TCP handshake ACK traffic going to the other box?
