after connecting to the firewall the download speed is greatly reduced. TZ600_SonicOS Enhanced 6.5.4
I have a 50 Mbps leased line. This gives me 5 to 6 Mbps download speed when I connect the ISP cable directly to the laptop/pc. But after connecting to the firewall it only gives me 1 to 1.5 Mbps download speed. Even I enable only one user in that interface through routing.
why? any answers?
