HTTP Browsing extreme slow after Update SFOS to 17.5.6 from 17.5.3

Gemeinde Ismaning over 6 years ago

after Updating the XG310 to Firmware 17.5.6 the Internet Traffic is extremely slow and for users its not

possible anymore to surf the Web.

with Firmware 17.5.3 everthing is ok, so we rolled back to old Firmware.

Websites in IE11 and Firefox need about 2 minutes to load instad of 1 Second in old Firmware.

is this a known Bug or a feature to slow down users ? ;-)

Hi Gemeinde Ismaning

I would recommend to contact our technical support team and open a support case.

This required a thorough investigation.

thx for the Information.

a support case is open now.

possible Reason is maybe the using of an Upstream Proxy Port 80, but its not poosible to change.

we are adviced to use this port and its not other port possible.

internaly wi use the Sophos as an proxy with port 8080.

so since Update from MR3 to MR6 and now MR7 this is not working anymore, so for me its a new bug in the SFOS.

using an other upstream proxy port like 8080 it seems to wirk a litle bit better, but this is not allowed.
