This may be natural depending on what inspect (firewall) options you have enabled. Naturally, if the gateway doesnt need to inspect packets then traffic flows with less interference, but if you are inspecting packets for several characteristics, it may result in less than optimal throughput.

I have BT's fibre optic broadband and am supposed to get a max speed of 75mbps. If I use the router which is supplied by the provider I get roughly this. However if I connect my firewall (Netgear UTM5) directly to the modem I get a max speed of approx 53mbps. If I connect the modem to the provider supplied router and then the provider router to mine everything works fine. I checked to make sure the connection is running at full duplex and also have tried 2 different modems made by 2 different manufacturers but still no change. <br />
<br />
I am also seeing the same behaviour on another of my networks which has the same modem and a Netgear UTM9S<br />
<br />
What could be causing this strange behaviour?<br />
<br />
Any help is greatly appreciated

broadband performance

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Routers

The term broadband commonly refers to high-speed Internet access that is always on and faster than the traditional dial-up access. Broadband includes several high-speed transmission technologies such as digital subscriber line (DSL), cable, fiber optics, wireless (for which there is a separate topic), satellite and broadband over powerlines (BPL).

Broadband

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
