Throughput on DMZ port without UTM

wabla47

Hi
My Internet connection has a raw download speed of 1 Gbit/s. When I run a speed test directly behind my modem without going through the firewall, I get a DL speed of around 870-930 Mbits/sec.
If I run the same test connecting on port 7 of my USG110, where I have a security policy rule with no UTM service at all, the speed drops to around 300 Mbits/sec. 
Shouldn't I expect a higher speed there? Why does my USG slow down the speed so much even if I have not configured any UTM service on that port?

When I least tested the speed of my Zywall 110 which has the same Firewall throughput you might get 600Mb

Do the following for more speed

only problem is the option gets checked on reboot

Hi @wabla47,

Welcome to Zyxel Community. It should be able to reach 4xx mpbs without UTM service.
