on Version 2.2.6 then dist-upgrade Zentyal 2.2.7
Zentyal is our gateway firewall, DHCP, DNS & squid proxy
From the Zentyal Desktop we can access
www.usps.com.
Not one computer behind Zentyal can access
www.usps.com using transparent proxy and not using transparent proxy. But we can connect to
www.prioritymail.comWhen we had core 2.0 version last week, it worked. We had previously added /etc/ebox/hooks/firewall.postservice hook like this
iptables -t nat -I PREROUTING -i eth0 -p tcp -m tcp --dport 80 -d usps.com. -j ACCEPT
I have this in place again now here /etc/zentyal/hooks/firewall.postservice
I can have this in place or not, does not make a difference.
www.usps.com will resolve and Firefox shows "connecting..." and never times out or receives any errors. The Browser title does not change for
www.usps.com - When we go to holdmail.usps.com the browser title will change to "USPS.com - Hold Mail Service" but the page never loads. The URL in the address bar changed to
https://holdmail.usps.com/holdmail/ Firefox status says "Transfering data from holdmail.usps.com..."
The visible page at holdmail.usps.com never shows up, I stopped the loading, and looked at the source of the page, the source looks complete enough with 1715 lines & proper closing HTML tag
For this file (
http://www.usps.com/ContentTemplates/images/global/usps_logo.gif )on the usps.com site, I see in the "Maintenance > Logs > HTTP Proxy " (when I have the transparent proxy enabled)
I see these details:
Event = Accepted
Bytes = 0
Mime/type = -
Please any advice/suggestions will be greatly appreciated.
Bless You
--Update
We are not using proxy in transparent mode.
there are a number of websites we are experiencing trouble with.
a similarity I see with the problematic connections is SSL
do.com
fonts.com
