Gateway errors when proxy forwarding to the Cloud

Solution

Overview

Browsing websites will randomly display "gateway errors".  A refresh of the page will load the content correctly.

Cause
Resolution

One possible cause of this is that ports are being reused too frequently from the child proxy.  If this is the cause of the problem confirm the following settings on the child proxy:

#config term
#(config) tcp-ip inet-lowport 16384
#(config) tcp-ip tcp-randomize-port enable
#(config) exit

These settings will enable 48K source ports to be used instead of the default 16K.  It is always good to have tcp randomization enabled for security reasons.
