Good day everyone. My problem is the next I have an macbook pro with os x 10.5.8 with squid and ipfw running as a proxy. In my company I don't want people to connect to facebook neither twitter. My squid configuration is running correctly, my only problem is configuring the ipfw to force users to use port 8080. my ipfw conf is: Code: 00010 divert 8668 ip from any to any via en0 00100 allow ip from any to any via lo* 01010 allow ip from 10.0.2.0/24 to me dst-port 8080 01011 allow ip from me to any 65535 allow ip from any to any being en0 my internet connection and en1 my airport shared connection The problem is that user still can connect to internet without configuring their proxies. what am I doing wrong?
