I have my proxy server in the LAN. The proxy cache all of the http sessions inbound and outbound of the LAN. In the LAN, user must enter the proxy setting in the browser to be able to surf internet(http port 80).
1) How the setup in the cisco router 2821(ISR-all firewall,nat and IGW)) to cater the proxy server in the LAN? What is the rules to be injected into the configuration so that user will only go through PROXY server and then go through the router?
> but if we block the incoming traffic from LAN-subnet for port 80 & 443,
> the sessions that been originated from LAN-subnet will be blocked (source IP),am i right?
> So,how the router will recognize that session that originated from LAN-subnet through proxy-server-ip?
Notice, there is a permit for the proxy server IP address in the ACL
