Hi, I have 2 computers, let say A :192.168.0.10 and B : 192.168.0.11 For A, Squid 2.6 Stable1, DG 2.9.7.1 are installed. For B, Only DG 2.9.7.5 is installed. My purpose is; Squid must listen only 127.0.0.1:3128(for comp. A) and 192.168.0.28 for requests from Computer B's IP. Other connection requests should be discarded. All requests should be forwarded to squid from DG installed on A and B. To do this; I changed http_port to 3128 from 127.0.0.1:3128. In this case, any client who can change his/her proxy settings is able to connect proxy directly.(As expected) This works, but not suitable for my purpose. What will be the correct conf?
