Hi Could you please help? We have ISA 2000 proxy cache server---------------packet shaper--------ISA2000 firewall server----internet Packet shaper to control bandwidth and all p2p traffic and we have different package for different users which mean some users can have 512,and others can have 1 meg bandwidth and so on, based on their IP addresses The problem is the users who are configured as web proxy client their request will reach the packet shaper as proxy server ip address and not user ip address so the packet shaper will not do any control based on their ip address. We need to keep the proxy cache for performance and traffic. Any idea what we can do, is ISA 2004 has solution for this problem? Regards Hanan
