1. I have a main virtual server "vs_main" that gets all non-http traffic it is (performance layer-4)
no profiles but a single iRULE showing debug if needed on just 'connections'
2. I have a focused virtual server "vs_main_http" that gets port 80 traffic (but in the above posting
NOT 8002 traffic) it is (type: Standard - with a HTTP/httpclass profile
-- Perhaps when I select the virtual server for :8080 it goes to vs_main (and there is NO
HTTP/httpclass profile) this might be my entire issue.
It also might explain why "I needed to create virtual servers with HTTP/httpclass profile's"
on top of my LB node pairs to get anything to work at all.

I retested (moving the def_server line) no luck - BUT the key was to enable
"port translation" on the VIP - thanks to your pointer (different post).
Obviously I don't fully grasp all the concepts of the F5 there but I am learning

Interesting, I still have one question how does one "force" the VIP's default pool
Thanks in Advance
