Virtual Server to front end and direct traffic to proxies

We currently use Big-IP's 4.6.2 to front end proxy servers and direct traffic according to destination (either the internet or our parent company) and our internet browsers have explicit proxies set. What I am running into now that I am throwing a V9 Big-IP inline for testing is that the IP I have setup as the proxy IP address is getting forwarded to our proxies as the destination IP address - which obviously is incorrect.

Our rule looks something like this:

when HTTP_REQUEST {
  snat automap
  if {[HTTP::host] contains $:ARENTSITES} { 
    use pool parent_fw_webproxy.p
  } elseif { [HTTP::method] eq "CONNECT"} {
    use pool internet_fw_https.p
  } else {
    use pool internet_fw_http.p 
  } 
}

I am not sure if it is something in the iRule (though I don't think so because I backed the iRule off my virtual server and made my virtual simply point to my internet pool and still could not access the internet) or the virtual server. Seeing as though I am leaning towards it being a virtual server configuration problem or a SNAT problem I understand this isn't the best place to post this but there are enough smart people in here that someone might be doing the same thing and could throw me a bone.

Thanks
