anyone tried to forward all http traffic from WLAN to the LAN's proxy ? 
each has its own subnet.
I'm portforwarding all traffic on port 80 from the WLAN interface to the 
proxy in the LAN segment
but i alwys get an error from the proxy that the url:  /_  is invalid.
does anyone have a solution for that ?

thanks    Serge
