This can be other problem instead of squid problem. But, I hope someone in this list can give some clues ...
Here is the situation in my place : Some (but not too many) users have to dial to a cisco dial access server to connect to internet. Until yesterday, this dial access server have been configured to NAT every user dialling to it, and is routed to the firewall. FYI, everything in our network is behind that firewall. We want all users using dial access to be routed to squid proxy server, not directly to the firewall. What we have done is simply to change the route to 0.0.0.0 (internet). If all users (using dial access) used to go (directly) via firewall whose ip address is 10.0.0.1, then now they are routed to 10.1.1.1 which is the squid proxy server address. But alas, even after setting the browser to use 10.1.1.1 as its proxy server, and even ping can be done from both sides (from client and from the proxy), I still can surf internet from a dial access... Any shares and helps would be very appreciated Regards aqil
