WatchGuard firewall--Unsafe URL


#1

Hi all,
I have an error when trying access to some files.
It shows:
WatchGuard firewall: Request denied for http://208.113.18.20:80/home/1/truyen/truyenma/bai_nao.wma: Unsafe URL `/home/1/truyen/truyenma/bai_nao.wma’ denied

Could you please tell me why and how to fix it ?
thanks a lot
