Hi, I am accessing squid through a PPTP tunnel and have a lower MTU as a result. I am able to use squid ok as an explicit proxy however when trying transparent interception many pages timeout and don't open. I guess this is because of MTU issues. I have tried "http_port 3129 intercept disable-pmtu-discovery=always" but to no avail. I am using 3.2.0.17. Any ideas? Thanks Daniel
