TCP_DENIED/403 3954 CONNECT www.welt.de:443 - HIER_NONE/- text/html

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I run a home server under Centos 7 and squid 3.5.20. The config is still work in progress as I started only today. Any tipps&tricks are welcomed
The function is as expected when working from my LAN. But when I tested today from my cell phone from outside I received a few TCP_DENIED for web pages that are not part of the blacklists and I can access from my LAN.
I also tried a few apps (e.g. Twitter, Linkedin, etc..) and none worked. Underneath the config as-is.

Any idea why I cannot connect?
I have two more question I fiddled with and has no success:
  • Is there a possibility to re-direct certain MACs from the LAN through Squid and others can go direct?
  • Is there a good howto that describes in detail how autdetect proxy works with wpad.dat. I want that when users are on LAN they go through squid, but when they are travelling they can go direct.
Thanks for your help,

Wolfgang
