When people dial into our network using a modem & try to access the
proxy, the browser always times out, even though the proxy server is
up in the browser settings. The IP address of the modem dialling in is

allowed access through the proxy using access rules. We have ISDN
cards &
routers dialling in via the same service, with the same settings &
can use the proxy with no problem. Does anyone have any clues about
this might be happening?
