I have a CERN caching proxy running on a sun ultra sparc machine. The
proxy server is bounded to the port 82 of that sun machine. A
Livingston Internet Router with dial-in facility is also connected to
the network. This Livingston router does support IP filtering. We use
this feature to set up IP filters on each dial-in port of the router.
As a policy a http request on port 80 is restricted to the local
network. That means if a http request is made on port 80 for any
other web server out side the local network it is blocked by the
Livingnston IP filter. However if the dial-in user wants to access
any other web site he/she can send a request to port 82 of our
caching proxy server.
This set up works with any browser as long as the users browse the
internet. However if a file is down-loaded through a web page the
browsing session gets hang on. But this doesn't affect on the dial-up
connection. It retains perfectly but transmission does not contnue.
Is this a bug or something wrong with my configuration file. But the
same file can be properly down-loaded without going through this
caching proxy server provided that IP filters are not imposed to
restrict htttp requset on port 80.
Can anybody enlight me on this issue immediately.
