viking 猫的ZIPB试验成功，好玩~~~

以前一直都是用NAT模式的，今天尝个新鲜，试了一下ZIPB模式，不用再怕session超标了，哈哈。

怎么图片不显示？

发现只有支持一台机？
其他朋友有没使用的经验？

copy过来的，将就着看吧。
(aka. "The Mysterious zipb mode")
zipb mode, (aka. "ZIPB mode", aka. "half bridge mode") is how you turn your super-dooper NAT-enabled, firewall-protected voyager viking router into "just a modem".
With zipb mode you can put a local device directly onto the internet, be it a computer, another router, WiFi Base station, whatever, the voyager will effectively become invisible (at least from the outside), you even get to keep the firewall.

The manual says..
Advantages of the ZIPB mode.
does not require you to install any software on subscriber PCs [nor does regular ethernet use -ed]
does not require you to run NAT on the modem
allows you to manage modem for both LAN and WAN sides, because the modem has an IP address on both LAN as well as WAN interfaces.
allows you to run Firewall/filtering feature on the modem.
allows you to use bandwidth efficient PPPoA, on the modem';s WAN interface.
the LAN-side device gets the PPP IP address allocated to the modem using DHCP.
For many, the main advantage of zipb mode is that you get to bypass the Voyager';s NAT, and therefore bypass its limit of 511/512 simultaneous connexions which is too small for certain applications. Whether or not this is actually the case, the jury';s still out.

继续抄
To set up zipb mode, follow these steps..
1. Ensure the Voyager';s DHCP server is enabled..
The external IP is given to the Voyager and then passed on to your device via DHCP, so the Voyager must have its DHCP server enabled. Ensure there is an active DHCP server pool with poolid=0, with at least one free local IP for your device.
create dhcp server pool poolid 0 start-ip 192.168.1.3 end-ip 192.168.1.99 mask 255.255.255.0 gwy 192.168.1.1
you may prefer to specify a smaller pool, or a shorter lease time..
create dhcp server pool poolid 0 start-ip 192.168.1.3 end-ip 192.168.1.5 mask 255.255.0.0 gwy 192.168.1.1 lease 60 mlease 120
Whatever, so long as it works. Now switch the DHCP server on..
modify dhcp server cfg enable
This page will state the DHCP Mode as "DHCP Server".

2. Disable NAT
In a telnet session, do..
modify nat global disable
3. Enable ZIPB mode
The zipb mode admin page will correctly state whether or not zipb mode is enabled, but setting it there doesn';t seem to "stick", so in a telnet session, do..
modify zipb cfg enable
4. Set the PPP interface to "StartOnData"
This will bring up the ppp interface as soon as it detects DHCP requests on the local ethernet. This is generally set when you create the ppp-0 interface, but you can set it separately, just in case..
modify ppp intf ifname ppp-0 startondata
5. Save settings
The important bit that lots of folk forget. In a telnet session, do..
commit
6. Finally, ensure your device is set to be a DHCP client
The router will dynamically assign the device your external IP address, so you need a DHCP client running on that device. If it';s a computer running XP, simply open the properties for your local connection (TCP/IP Properties) and set it to "Obtain an IP address automatically". If it';s a router or similar, tell it to "get IP address via DHCP" or some similarly worded option.
You can probably set the machine';s alternative IP address to your some static LAN IP address, something like 192.168.1.3

That';s it!
If all goes to plan, your device should have been assigned a fresh IP from your ISP';s pool, and you are live on the internet, bypassing the voyager';s NAT altogether.

这个有什么用啊?
怎么开ZIPB模式啊?

谁在啊 ？ 我有个问题请教

小知识：关于ZIPB
　　先从它的名称来看，翻译过来就是免安装PPP网桥。让我们分析这个名称，ADSL modem最常见的两种工作方式，一种是网桥模式，由主机进行拔号，ADSL做为透明网桥工作，这种方式下机器要上网就需要安装拔号软件，而公网IP是直接属于上网机的。一种是路由模式，这种方式下又有两种情况，一种当ISP给静态公有IP时，直接把该IP绑在ADSL modem上，另一种是由ADSL modem拔号来获得一个动态的公有IP，无论哪种方式，内网主机需要上网需要有内网的IP，把ADSL modem设为网关，主网机上无需安装拔号软件，它的好处是可以提供多机同时上网，不利之处在于有些应用软件在NAT上使用会有问题，需要做一些额外的设置来让这些软件正常工作。现在我们来看ZIPB。它的工作方式介于两者之间，一方面，它由ADSL modem来拔号，这样上网机不用安装拔号软件，同时，它又处于网桥模式，这样，拔号获得的公网IP是属于上网机而非ADSL modem，因此，上网机不用工作于NAT下面，就好象通过网桥直接连接在公网上一样。可以看出，这是一种很方便的上网模式，一方面，无需客户机来进行拔号，对于一些没有内置拔号软件的系统如win98等省了很多麻烦，另一方面，由于可以直接获得公网IP，一些在NAT下受限的网络应用再也没有了使用障碍

是不是只能一台机可以，共享的其他机子是不是要设固定的IP才可以上网？
