OK, first off, if you are using a monitor for web servers listening on port 80, use a custom HTTP monitor to test the servers. I usually start with a GET /\r\n\r\n as the monitor and wait for a 200 OK response. You can get more specific, but that is just a baseline. Use a tool like fiddler or HTTPWatch to get more elaborate.

 

 

Second, I also see that you are using a FastL4 profile. I wouldn't necessarily do that either, it make the VS a regular Layer 7 one, allowing more flexibility, highes Load Balancing Functionality, and iRule functionality.

 

 

Third, you might want to turn on SNAT Automap. This may be an asynchronous routing issue.
