CERN caching proxy problem



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
