The devices are running various firmware (17.5.8 MR-8 on the head office device). I've edited TCP timeouts and stripped rules back to the minimum.

I feel that this might be an issue with the website, but they claim that it cannot be. I've found entries in conntrack, but I'm struggling to determine if that means that the web server isn't replying, or the Sophos isn't replying to the Web Server. It manifests as 'Cannot reach this page' errors in IE and various site specific errors. It occurrs at multiple sites thorugh multiple Sophos devices.

Our client is having lots of issues with their web based Line of Business application.
