I have installed a bordermanager 3.7 and a microsoft web server in my
company. The border manager server has a NAT to the web server. Internet
users could access to our website fine but when an internal user, from
inside the company tried to access to the web site trought DNS name or
public address from one internet explorer with the proxy setting activated
the following message appears

HTTP Error
Status : 504 Gateway Time-Out

Description : Unable to connect to origin Web server.

How can i solve that ??? to let internal users access to our web server. I
tried to add a record in the hosts file of the bordermanager server but it
didnt work.
