SDN 101: An Introduction to Software Defined Networking
Discover the advantages of SDN.
SDN has quickly become one of the hottest trends in IT. But not all SDN solutions offer real software-defined functionality. As more enterprises consider SDN, they want to know, “What is SDN? And what are the real benefits?” If you're ready to explore the advantages of SDN, and want to know how it should be implemented within your enterprise, start by reading our introductory white paper.

I've got a question about, as the thread title suggests, whether a cheap modem/router configured to use a Smoothwall box as a DMZ can alleviate any issues with CPU/RAM usage on the cheap modem.
I'm building a relatively large scale OpenVPN deployment (up to 1000 users at any one time), and obviously a cheap Dynamode modem/router ain't gonna handle that kind of stick. I've got a few options...
My current thinking is to configure the Dynamode router to use the Smoothwall box as a DMZ (ie forward all ports to it). The only thing is, I'm not sure whether this will help with CPU/RAM usage on the modem/router. Any hints would be much appreciated.
My second option is to use some kind of half-bridge mode on the Dynamode to give the Smoothwall box an external IP on it's external interface. I've never used half-bridging before, nor do I have any idea if Smoothwall supports this, or how to go about configuring it.
The third option is to try to get hold of a USB modem/router (e.g. Thomson Speedtouch 330 or D-Link DSL-200) for Smoothwall to use to connect to the ISP itself.
Any help on any of these gaps in my knowledge would be greatly appreciated.
i'm thinking :
how about full bridge mode on the modem - so your link directly connected to your smoothwall? i'm looking at modem's capability to handle both physical link and routing? too heavy for "cheap" modem, not to mention some DoS attacks to the modem (it has very limited resource). so that the smoothwall become the router/firewall - just give it a better machine.
full bridge mode modem ---- (PPP/PPPoE etc using RJ45)monowall(internal) ---- LAN (subnet1 for servers/DMZ, subnet2 for regular LAN client)
depends on your connection - was it and xDSL or something,
if you rent a cable internet - than you should note that there is a small modem/adapter connected between your computer/router and the coax cable. that is a bridge mode modem - basically it just passed your IP traffic directly to your computer/router while it only does some layer 2 functionalities.
Thanks, I think I understand some of this... If the ISP uses PPPoA, and my modem/router is in full bridge mode, then in Smoothwall, do I use PPPoE, because there's no option for PPPoA unless I use a USB modem?
