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.

Can someone help with my issue ? I've done all I can think of, and I'm starting to think a static route isn't the way to go.
So I have a box sitting in a DMZ acting as a reverse proxy with Apache, it routes the DMZ traffic to the internal website(s).Running Centos 5.4
For this i will use 192.168.0.XXX for the DMZ addresses and 172.20.250.XX for the internal address. I don't know the details on how the DMZ is setup (not part of that group)
So if someone from the outside world connects to say stuff.bobswebsite.com(DMZ address 192.168.0.200) apache will pass that traffic to the internal host server1 (172.20.250.50).
Now, this box has has two network cards in, due to limitations with SSL sites you can't run more then one SSL virtual host per IP. so eth0 has the DMZ address of 192.168.0.200, eth1 has the address of 192.168.0.201
The firewall is configured to only allow 192.168.0.200 to connect to the internal address of 172.20.250.50, and 192.168.0.201 to connect to 172.20.250.51. The problem is when configuring a site on the second NIC stuff2.bobswebsite.com(DMZ address of 192.168.0.201, and a internal address of 172.20.250.51) all traffic still leaves as eth0 (interface with the default gateway), thus being blocked by the firewall.
I have added the following to route-eth1 per the centos howto i found.
1. Change the NETMASK of my router and my eth0 to 255.255.255.128
2. Change only NETMASK of my eth0 to 255.255.255.128 (I didn't get an error with this setting, but couldn't ping the GATEWAY either)
3. There is no need to mention that I restart my network in each of the step.
Thx in advanced
P.S I hope to find a solution but in the mean time I'll try to set my router to DHCP without changing the local LAN address
And maybe then try to do some changes again. If that's not going to work I'll go back to my original setting.
