Hello,

I setup a squid as transparent proxy on CentOS7. I setup squid with IPtables with NAT and now if want to setup internet by setting up a proxy setting on browser from client internet is not working and i am getting "TAG\_NONE/409 4347 CONNECT [www.google.com:443](http://www.google.com:443) - HIER\_NONE/- text/html" error in /var/log/squid/access.log.

But without proxy setting in browser internet is working fine. While googling in found to setup dns\_v4\_first on in squid.conf but still the same issue.

Can you please help me to figure out this issue.
