Add some extra config to Squid3 VPS

<------------------- General info -------------------> Before explaining, we want to be very clear that we're a Web Agency and we're looking for long term providers that are affordable and also very experienced with lots of years working on hosting environments / very experts in WooCommerce in this case. Very honest people, if you do this fine we will give you more tasks of other projects, since we're an agency and have multiple clients / projects, most of them based in WP. == General requirements for any freelancer in this kind of tasks - Have a good english (we also talk portuguese and spanish, just in case you use any of this languages). - Better if you're a linux administrator / webhosting sysadmin - Must have skype account, better if we can talk directly via voice / cam in special cases - Available for long term deals and other future projects - We want freelancers that fixes issues in minutes, not in hours. At least 5 years experience per area. <------------------- General info -------------------> In this case we need to add some extra config on squid3 in a VPS to make this: 1.- Assign outgoing IPv6 per user 2.- Tune the config so speed is as fast as possible, now all works OK but some mess maybe coz of DNS ? 3.- We can use multiple ports or use just one incoming port (8081) As you can see, this is a very easy and fast task. Thanks.
