Hi Eliezer, I understand what you say, but we use external IPs for our network hosts (nothing in 192.168.x.x range). What I need is to direct the traffic to our proxy using the wpad mechanism (which works just fine for us) but to make our proxy completely transparent to external destinations. I think TPROXY Squid might be a way to do it, but we only use Squid 2.7 now. We want to keep running with our Proxy in the same deployment scenario, except that we need external Internet destinations to see the requests coming from our hosts IP(s) instead of our Proxy. Thank you for your insights, Julian -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/source-address-ip-spoofing-tp4667417p4667440.html Sent from the Squid - Users mailing list archive at Nabble.com.
