個Server 終於起返了

由於和記VDSL 上網問題，我是用Debian Sarge 做NAT server 上網，不過今天開始不能突然上不到網。以前用開的setting 未改過，而且用開也沒有問題。只是在Linux Server 不能夠上網，雖然我用ifconfig 可以?到ip ，但是ping 去其他地方(如yahoo.com / gmail.com) 只是resolve 到這個 Page (218.191.252.206)。看過plog 睇?好似有派到ip，不過上不到網。如果我將條cable 用winxp ，又上到網。

Some experiences share with you all:

和記 help me to changed a vdsl modem and I need to pppoe (rp-pppoe v3.5) to login .

In my linuxbox rh9, I do the adsl-setup, I can get the public ip and dns.
I found the following problem:

1. I get ping the first dns server 210.0.128.241 (but I can ping the second one 210.0.128.242
2. I can\'t browse all web site. (It always redirect me to the HGC\'s first startup page)

After I look into the routing table I found that a defaullt route is missing (when compare it wth winxp).

I did the followng then I can browse all website:

1. run adsl-setup: enter DNS ip manually: 210.0.128.242 and 210.0.128.216.

2. add a default route in /etc/rc.d/rc.local
route add -net 0.0.0.0 netmask 0.0.0.0 ppp0

But I dont\' know why the rp-pppoe can add this route automatically.
The DEFAULTROUTE option in /etc/ppp/pppoe.conf already set to yes.

And I got disconnect 2 times today (It was happen when using DCHP before)

Hope this can help anyone hit this issue.
