without further description of your topologie, this sounds like your 
proxy tries to fetch a page from the site that resolves to an official 
ip, your system only knows the default route via FW and it is routing 
the request back "in"...
Is your FW performing any NAT for the unproxied HTTP-Host?
If so, you have two options:

- Rewrite the request to the internal IP/Port

- ensure that the the proxy resolves to the internal IP for requests
e. g. via local HOSTS file or local DNS Cache...
