Connect two Yamaha RTX via VPN with dynamic global IP

Connect two Yamaha RTX via VPN with dynamic global IP (of course, one side must have a fixed global IP)

PPTP VPN on Yamaha RTX

This is to set Yamaha RTX as PPTP server waiting for connection from clients.

Filtering packet at tunnel on Yamaha RTX

Filter setting from Web UI is only possible for PP, but via command line filtering tunnel is also possible, for example:

ip filter 201010 pass * 172.31.31.0/24 icmp * *
ip filter 201011 pass * 172.31.31.0/24 established * *
ip filter 201012 pass * 172.31.31.0/24 tcp * ident
ip filter 201013 pass * 172.31.31.86/32 * * *
ip filter 201014 pass 10.0.10.254/32 172.31.31.0/24 * * *
ip filter 201015 pass 172.31.31.0/24 * * * *

tunnel select 2
tunnel encapsulation ipip
tunnel endpoint address 172.25.111.3
ip tunnel tcp mss limit auto
ip tunnel secure filter in 201010 201011 201012 201013 201014 201015
tunnel enable 2

This is, use "ip tunnel secure" instead of "ip pp secure" and put this line after "tunnel select".

Hackintosh on LG X120

Download NetbookBootMaker
http://code.google.com/p/netbook-installer/

Create the installer USB disk from Leopard DVD as mentioned here
http://www.mydellmini.com/forum/mac-os-x-guides/12595-netbookinstaller-1-usb-installation-via-mac.html#post99604

With the USB boot disk, boot and create 2 partitions as mentioned on this "Example 2: GUID Multi-Boot for Windows XP"
http://osx.mechdrew.com/guides/advanced2.shtml

Then proceed with install.

The X120 will be installed with Leopard and working Ethernet. Do a software update, which will update it to 10.5.8, then reboot. Screen will just be blank. Do a safe boot by typing -x on Chamaleon screen. Then run Netbook installer, install all. Leopard will then boot normally. But ethernet will no longer work.

LG X120's WiFi is using Realtek's rtl8187se. This is the same card as MSI Wind, and there is already a driver for MacOS. Install the driver to enable WiFi.

Use this to enable ethernet again

FG with Yamaha RTX

For 端末型払い出し just routing the traffic cannot connect two networks, so tunnel must be made to connect two networks via router.
There are 3 types of tunnel supported by Yamaha RTX:
-IPIP
-PPTP
-IPSec

There is no way to properly set Yamaha RTX via web for unnumbered PPPoE when multisession is set via the web. The easiest way is to first set PPPoE multisession, and then add the following settings via command line (assuming the unnumbered PPPoE is at pp1):

pp select 1
no ppp ipcp ipaddress on
nat descriptor address outer 1000 [router's IP address]
nat descriptor address inner 1000 [first private LAN IP address]-[last private LAN IP address] [router's IP address]


Or, when using wan side IP other than router's IP:

pp select 1
no ppp ipcp ipaddress on
nat descriptor address outer 1000 [router's IP address]
nat descriptor address inner 1000 [first private LAN IP address]-[last private LAN IP address]

Optimizing Windows Media Services

This article provides a technical overview of the performance and scalability of Microsoft Windows Media Services 9 Series (including the Windows Media Services update released with Windows Server 2003 Service Pack 1.) It describes common Windows Media Services performance issues, limitations, and performance monitoring techniques. It also presents the results from a set of performance tests conducted in a controlled lab environment.

It is recommended that you use the information presented in this document as a guideline. The performance results are based on specific hardware configurations that represent simplified versions of real-world scenarios. The actual capacity of your streaming media system depends on several factors, including network topology, user utilization patterns, hardware configuration, and software configuration. Based on the guidelines and performance information in this article, you should be able to design, fine-tune, and maximize the capacity of your servers to achieve the best results for your individual situation.
