###############################################################################

# TAG: ppp
# Path to the pppd program, default '/usr/sbin/pppd' on Linux
#
#ppp /usr/sbin/pppd

# TAG: option
# Specifies the location of the PPP options file.
# By default PPP looks in '/etc/ppp/options'
#
option /etc/ppp/pptpd-options

# TAG: debug
# Turns on (more) debugging to syslog
#
debug

# TAG: stimeout
# Specifies timeout (in seconds) on starting ctrl connection
#
# stimeout 10

# TAG: noipparam
# Suppress the passing of the client's IP address to PPP, which is
# done by default otherwise.
#
#noipparam

# TAG: logwtmp
# Use wtmp(5) to record client connections and disconnections.
#
logwtmp

# TAG: bcrelay <if>
# Turns on broadcast relay to clients from interface <if>
#
#bcrelay eth1

# TAG: localip
# TAG: remoteip
# Specifies the local and remote IP address ranges.
#
# Any addresses work as long as the local machine takes care of the
# routing. But if you want to use MS-Windows networking, you should
# use IP addresses out of the LAN address space and use the proxyarp
# option in the pppd options file, or run bcrelay.
#
# You can specify single IP addresses seperated by commas or you can
# specify ranges, or both. For example:
#
# 192.168.0.234,192.168.0.245-249,192.168.0.254
#
# IMPORTANT RESTRICTIONS:
#
# 1. No spaces are permitted between commas or within addresses.
#
# 2. If you give more IP addresses than MAX_CONNECTIONS, it will
# start at the beginning of the list and go until it gets
# MAX_CONNECTIONS IPs. Others will be ignored.
#
# 3. No shortcuts in ranges! ie. 234-8 does not mean 234 to 238,
# you must type 234-238 if you mean this.
#
# 4. If you give a single localIP, that's ok - all local IPs will
# be set to the given one. You MUST still give at least one remote
# IP for each simultaneous client.
#
# (Recommended)
localip 192.168.217.1
remoteip 192.168.217.234-238,192.168.217.245
# or
#localip 192.168.0.234-238,192.168.0.245
#remoteip 192.168.1.234-238,192.168.1.245

@grindsgears 谢谢，已经检查 net.ipv4.ip_forward = 1

配置iptables 也做了，还是收到不包，能发送出去！

自动脚本安装的结果， IPAD 连接不到服务器，晕了， 对了脚本中有几个包的地址失效了，需要网上找替换的地址！

@terry0824 我现在很困惑，那个文档有问题还是有什么其他办法确定一下问题呢？

@donnior 我现在又该下试试！

PPTP的帐号 btwo/phoenix 主机是106.187.102.170

各位：有L2TP over IPSec 的安装教程吗？最好是已经验证过的，不是想吃现成的，实在是不想太折腾了！！谢谢各位了！

HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Tcpip 下面有很多个MTU 都是1300 ，修改了十四号
@ratazzi

@lanbing 这个不错，自动配置的， 我自己配置postfix被害苦了，呵呵

补充： 我用得是WINDOWS的环境，是不是和本地编码也有关系，网上找了些资料看，都是几个编码的问题，新手看得有点晕乎了！

1.

print r.text

由于没解决问题，只测试了下。


2.
str= s.replace(r'\r\n', '\n').replace(r'\"', '"').replace(r'\/', '/').replace(r'\t', ' ') 我现在是这样替换的，感觉处理不完美，肯定有更好的解决办法。

3.
