gradeMode 下，所有 traffice 都走 VPN

[GoogleCodeExporter]

請描述一下您進行怎樣的操作之後碰到了問題
1. autoddvpn 运行正常，区分国外和国内访问没有问题
2. 按照 wiki 里 graceMode 配置办法，一步不差的配置 graceMode
3. 访问 ip.cn 和 whatismyip.org

你期待是怎樣的結果，然而卻出現了什麼情形？
期待 ip.cn 显示国内的 IP 但显示的还是 VPN 服务器的 IP
請提供以下資訊：

1. 您的路由器型號：WRT320N
2. DD-WRT版本：DD-WRT v24-sp2 (10/26/10)
3. 您的作業系統：OS X 10.6.6
4. 您的瀏覽器版本：Chrome 10, Safari 5
5. autoddvpn的運行模式(pptp+wget, pptp+jffs, openvpn+jffs等)：
6. DD-WRT WAN口連線模式是 pptp or dhcp or static ：
7. 運行autoddvpn之後DD-WRT 的命令輸出 # route -n  | tail -n 20 ：

如果方便的話，請參考這裡的說明，貼上autoddvpn.log內容
(說明：http://code.google.com/p/autoddvpn/wiki/DEBUG)

最後如果可能的話，請附上截屏或任何可能有幫助的夾檔

要注明的是，因为我是 static IP 所以 DNS 没有 DHCP 
需要自己填入，我填的是 ISP 给的 DNS，原因是否在这儿？

我在 /tmp/openvpn.log 里看到有两行：
Fri Aug 10 07:30:26 2012 /sbin/route add -net 0.0.0.0 netmask 128.0.0.0 gw 
10.6.9.5
Fri Aug 10 07:30:26 2012 /sbin/route add -net 128.0.0.0 netmask 128.0.0.0 gw 
10.6.9.5

我把这两行删掉，似乎就好了。
~# /sbin/route del -net 0.0.0.0 netmask 128.0.0.0 gw 10.6.9.5
~# /sbin/route del -net 128.0.0.0 netmask 128.0.0.0 gw 10.6.9.5

在 myip.cn 和 whatismyip.org 下都显示的是 wan 
ip（没有实现分别显示 wan ip 和 vpn 
ip），但是访问被墙网站都没有问题。

这个是为什么呢？

graceMode只有被牆的網站才會走vpn
這兩個檢查ip的網站都沒有被牆
所以你是正常的。

谢谢。我到把graceMode只有被牆的網站才會走vpn给忽略了。

不过如我上面所说，必须手动删掉两条路由，graceMode 
才能工作这是为什么呢？

你的openvpn設置可能不正確，可以的話把你的設置貼上來或截�
��吧。

以下是我的 server.conf 我在想是不是最后一行

push "redirect-gateway def1"

这个造成的？dd-wrt 的设置中要求去掉这一行，server 
上也要相应去掉？

# If you want to control access policies
# over the VPN, you must create firewall
# rules for the the TUN/TAP interface.
# On non-Windows systems, you can give
# an explicit unit number, such as tun0.
# On Windows, use "dev-node" for this.
# On most systems, the VPN will not function

# Configure server mode for ethernet bridging.
# You must first use your OS's bridging capability
# to bridge the TAP interface with the ethernet
# NIC interface.  Then you must manually set the
# IP/netmask on the bridge interface, here we
# assume 10.8.0.4/255.255.255.0.  Finally we
# must set aside an IP range in this subnet
# (start=10.8.0.50 end=10.8.0.100) to allocate
# to connecting clients.  Leave this line commented
# out unless you are ethernet bridging.
;server-bridge 10.8.0.4 255.255.255.0 10.8.0.50 10.8.0.100

# Configure server mode for ethernet bridging
# using a DHCP-proxy, where clients talk
# to the OpenVPN server-side DHCP server
# to receive their IP address allocation
# and DNS server addresses.  You must first use
# your OS's bridging capability to bridge the TAP
# interface with the ethernet NIC interface.
# Note: this mode only works on clients (such as
# Windows), where the client-side TAP adapter is
# bound to a DHCP client.
;server-bridge

# Push routes to the client to allow it
# to reach other private subnets behind
# the server.  Remember that these
# private subnets will also need
# to know to route the OpenVPN client
# address pool (10.8.0.0/255.255.255.0)
# back to the OpenVPN server.

# To assign specific IP addresses to specific
# clients or if a connecting client has a private
# subnet behind it that should also have VPN access,
# use the subdirectory "ccd" for client-specific
# configuration files (see man page for more info).

# EXAMPLE: Suppose the client
# having the certificate common name "Thelonious"
# also has a small subnet behind his connecting
# machine, such as 192.168.40.128/255.255.255.248.
# First, uncomment out these lines:
;client-config-dir ccd
;route 192.168.40.128 255.255.255.248
# Then create a file ccd/Thelonious with this line:
#   iroute 192.168.40.128 255.255.255.248
# This will allow Thelonious' private subnet to
# access the VPN.  This example will only work
# if you are routing, not bridging, i.e. you are
# using "dev tun" and "server" directives.

# EXAMPLE: Suppose you want to give
# Thelonious a fixed VPN IP address of 10.9.0.1.
# First uncomment out these lines:
;client-config-dir ccd
;route 10.9.0.0 255.255.255.252
# Then add this line to ccd/Thelonious:
#   ifconfig-push 10.9.0.1 10.9.0.2

# Suppose that you want to enable different
# firewall access policies for different groups
# of clients.  There are two methods:
# (1) Run multiple OpenVPN daemons, one for each
#     group, and firewall the TUN/TAP interface
#     for each group/daemon appropriately.
# (2) (Advanced) Create a script to dynamically
#     modify the firewall in response to access
#     from different clients.  See man
#     page for more info on learn-address script.
;learn-address ./script

# If enabled, this directive will configure
# all clients to redirect their default
# network gateway through the VPN, causing
# all IP traffic such as web browsing and
# and DNS lookups to go through the VPN
# (The OpenVPN server machine may need to NAT
# or bridge the TUN/TAP interface to the internet
# in order for this to work properly).
;push "redirect-gateway def1 bypass-dhcp"

# Certain Windows-specific network settings
# can be pushed to clients, such as DNS
# or WINS server addresses.  CAVEAT:

# To force clients to only see the server, you
# will also need to appropriately firewall the
