Virtual server for ICAP traffic

I need to build a virtual server which will receive ICAP traffic on port 1344. I've built a standard virtual server listening on port 1344 with the ICAP servers in the pool also listening on 1344. Th...

What happens if:

1- Change the number of pool members to 1 so you're only ever forwarding to one server.

Once you do this, it should be almost exactly the same as directly connecting the ICAP and App Server.

      Interesting! Glad you're making progress. If you want to continue looking at it, I'd recommend to examine packet captures taken from the ICAP server of direct-connect and by-bigip-connect modes to see what the difference is. It may be something as simple as a NAT or duplicate IP, or a routing problem.
