web service issue
I have a web service that is being called through the Big-IP LTM on port 81. This just HTTP, no HTTPS. For some reason the web service won't load/respond but if you go to each server it works fine so ...

Robert,
The obvious things to look for in wireshark is two way traffic. Are you seeing traffic to your servers' ip addresses and corresponding traffic from the server's ip addresses? If you're only seeing traffic in one way, e.g. dest is always x.x.x.x but never source x.x.x.x then that indicates an issue. Also, if you install wireshark on your web servers and run a packet capture, again, you want to see traffic from and to the client ip / or if using snat the LTM ip address. If port 80 is working hopefully you'll see noticeable differences. Pop "port 80" in the filter bar and then "port 81" to see these differences (without the quotes).
Also, in the GUI statistics, if you select Pool Member stats (I think that's what it's called" do you see the connections increment when you try to attach? If not then the request isn't even been sent to the pool member.
Hope this helps a bit.
