Attack: General Notice

[Flexible]

Dear all,

Current I have a case that I can not know how to process so far?

I am using CheckPoint 4200 appliance as web gateway (proxy-nontransparent), I confirmed that IPS software blade already is disable.
But when my client try to access the website, some CPAS or picture can not load.

Tracking on log as the attached file. There is the reject action with attack General Notice as IPS software Blade.
Show in capture.png, client issue show in capture1.png (test on IE ,FF, Chrome web browser)

Try to sk121533 but no more information due to i can make sure network/routing/dns are working well

Appreciate your advice .

Thanks
Flexible

There's nothing wrong.

The Gateway could not connect to https://a.tiscali.co.uk (I checked, and I can't connect to that as well) and the result is the log line you are seeing.

Using developer tools in my browser I can confirm that a.tiscali.co.uk does not respond to a subrequest. And I'm not using a proxy at all.

See sk110013, section "Proxy errors"
