Hey, From this basic snippet of the email I can tell you: 1. using DNAT is wrong anyway for intercept proxy. 2. specifically for SSL-BUMP it's ^^^ the cause of most of your problems.
Since SSL-BUMP tries to to bump server first it should be able to knwo what server to bump while using DNAT you replace the dst IP + PORT with the proxy IP which makes it's impossible to "bump server first".
Use either REDIRECT or TPROXY instead to allow SSL-BUMP + server fisrt. Eliezer On 12/31/2012 2:37 PM, Swapneel Patnekar wrote:
Hello Everyone, I've successfully managed to configure sslbump with squid-3.HEAD-20121231-r12554. However, I am having troubles in configuring SslBump using Bump-Server-First in Transparent mode. Basically I don't think I have the correct set of directives/configuration parameters in squid.conf to check/test SslBump using Bump-Server-First in Transparent mode. Any help on making this work is much appreciated.
