How do i do this
I am after an install of a stable and secure flavour of Linux to run as
an _easily_* configurable router.
The router needs one LAN interface and two WAN interfaces, with many
specific rules needed as to what data goes through which interface.
These rules need to be simple to add, remove, and change. This must
include the ability to change rules automatically if a WAN interface
has had a certain amount of traffic within a month. MRTG type graphs of
WAN interface usage, including by port number, certain web sites, and
by (labelled) LAN MAC address are also needed.
One WAN interface would be for general browsing and certain games,
while the other would be for all incoming and outgoing emails, text
chat (Windows Live, MSN etc), certain websites (eg: youtube), FTP, and
If the first WAN interface reached a certain data usage within a month
then all traffic would go through the second interface. This would need
to revert to the usual rules once a specified anniversary date had been
passed. If possible something similar, applied by quota and per MAC
address, would come into effect daily.
All rules must be able to be applied or not by MAC address. In this way
one or more specified computers could always use the first WAN even
after the month's limit has been reached.
*easily configurable does not mean things like "-A FORWARD -i eth1 -m
state --state NEW,RELATED,ESTABLISHED -j ACCEPT", but more like "MAC
all, PORT 25, WAN 2" and "MAC 11:22:33:44:55:66, PORT all, WAN 1,

Until recently, IBM’s Power Platform was looked upon as being the system that hosted IBM’s flavor of UNIX and proprietary operating system called IBM i. These servers often are found in medium-size businesses running ERP, CRM and financials for on-premise customers. By enabling the Power platform to run the Linux OS, IBM now has positioned Power to be the platform of choice for those already running Linux that are facing scalability issues, especially customers looking at analytics, big data or cloud computing.
￼Running Linux on IBM’s Power hardware offers some obvious benefits, including improved processing speed and memory bandwidth, inherent security, and simpler deployment and management. But if you look beyond the impressive architecture, you’ll also find an open ecosystem that has given rise to a strong, innovative community, as well as an inventory of system and network management applications that really help leverage the benefits offered by running Linux on Power.Get the Guide
