Dear Friends,
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.
Regards
Sanath
