Installation / Dell 1950 / Dell 2950 / HP ML350 G5 NIC
« on: March 31, 2014, 02:02:07 AM »
Broadcom BNX Network Interfaces not coming online on Dell 1950/ 2950 / HP ML350 G5 / HP ML360 G5 Similar.
An error during boot up is briefly displayed similar to "Can't load firmware file bnx2/bnx2-mps"

Current workaround:
Please uncomment the following line in /opt/bootsync.sh:
#rmmod bnx2 && modprobe bnx2

Reset just to be sure everything works after boot up:
/etc/wanos/clean.sh

After reboot verify:
'ifconfig' should display tun0

FAQ / Will it work with only one device?
« on: March 27, 2014, 09:23:01 AM »
Can I use this with only one device?

Unfortunately due to deduplication and compression, both devices are required.

Installation / ESX vSwitch Topologies without physical NIC's
« on: March 25, 2014, 02:16:21 PM »
First see http://wanos.org/wan-optimization/?p=1324 for configuration without physical interfaces

Although it is best to run with physical interfaces, Wanos can run in-path without the physical network interfaces. Here are two more scenarios to achieve this:

1) When the routing function is handled by a virtual router or firewall that are not establishing encrypted tunnels, the Wanos device can be placed in front of the vRouter/vFW or on the Wan side in other words. Wanos is therefore placed between the router and the ISP.


2) When the routing function is handled by a vRouter/vFW and it also builds encrypted tunnels e.g. IPsec, Wanos can be placed between two vRouters/vFW's.


In both scenarios the lan0 and wan0 still needs to be in separate vswitches/port groups vlans with promiscuous enabled to bridge the traffic flow.

Installation / Firewalls
« on: March 17, 2014, 10:06:48 AM »
When a firewall is used in the WAN in-between two Wanos appliances, it needs to permit IPComp (IP Proto 108) traffic and TCP option 76.
GRE Encapsulation is also available.

UDP Encapsulation is often the simplest method to work around firewalls, but introduce additional overhead.

Configuration / Traffic Policies
« on: March 16, 2014, 02:13:34 PM »
Traffic policies are optional in a standard point to point network, but recommended to ensure only the intended traffic gets optimized.

In a point to multipoint network, when some remote sites don't have Wanos devices, a Traffic Policy is required to by-pass these sites. For example in the following network, only one remote device is placed in the network at one site. Since there are multiple remote sites rule #98 and #99 are created:

FAQ / Wanos Open Source Wan Optimization
« on: March 08, 2014, 04:18:14 PM »
Is Wanos open source?
Can I have the source code?
Can I modify the source code?

Wanos Express versions released free will always be free, but not open source wan optimization per se. Opensource and Wan Optimization enthusiasts that are interested in contributing and making the technology more accessible are encouraged to get in touch.

Companies looking to integrate wan optimization into their feature set, should please have a look at the OEM Wan Optimization option.

How to help?
  • The easiest way to help is to simply start using wanos. Deploy in a network and let us know what the most essential next feature is.
  • Tell a friend, colleague, anyone that can benefit from wan optimization.
  • Wanos working well in your network scenario? Great, post the results.
  • Tell us about your hardware in the hardware section
  • Found a way to deploy the solution that has not yet been documented? Fantastic, let us hear about it and someone might benefit from this contribution.

Want more?
Developers, Linux and Networking skills are very valuable. Please get in touch.
