Hi Scott,
How are you making the HTTP request? Can you try this iRule:
when HTTP_REQUEST {
log local0. "[IP::client_addr]:[TCP::client_port]: Connected to [virtual name] [IP::local_addr]:[TCP::local_port]"
HTTP::respond 200 content "Connected to [virtual name] [IP::local_addr]:[TCP::local_port] from [IP::client_addr]:[TCP::client_port]"
}
Then start with a curl request on the LTM command line:
curl -v
http://1.1.1.1
where 1.1.1.1 is the virtual server address. If that works, then try from a browser. If the curl command works but you don't see a response from the iRule in a browser, then it's likely the request isn't making it to LTM.
