I have http proxy in transparent mode and all ipv4 is proxied and ipv6 is bypassed.
1. Any IPV6 is in the proxy bypass list. Screenshot1
2. If I try to download the test virus from eicar, I see my PC (IPv6) trying to connect to some strange IP but the mac is my astaro. Screenshot2.
3. During this time there is a delay of a few seconds before the astaro error screen pops up. Screenshot3.
4. Sometimes the astaro error screen has images removed from it when using IE8 sp2 vista[:S] but its very random and doesn't always happen. Screenshot4 and Screenshot5.
Interestingly this only happens on the initial request and not the subsequent requests . You can observe the same behavior by clearing the browser cache over and over[;)]
