VTWORAY 批量转socks5到PPTP（原创）

最近一个需求，需要装socks5协议转成PPTP来使用，本来考虑是使用tproxy的，但配起来没有那么顺畅（后来发现是socks5服务器没有搭好）最后用vtworay搭建成功，单进程可以转换多个，比tproxy多进程更方便

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

# 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/options.pptpd

# 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: vrf <vrfname>
#    Switches PPTP & GRE sockets to the specified VRF, which must exist
#    Only available if VRF support was compiled into pptpd.
#
#vrf test

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

# TAG: delegate
#    Delegates the allocation of client IP addresses to pppd.
#
#       Without this option, which is the default, pptpd manages the list of
#       IP addresses for clients and passes the next free address to pppd.
#       With this option, pptpd does not pass an address, and so pppd may use
#       radius or chap-secrets to allocate an address.
#
#delegate

# TAG: connections
#       Limits the number of client connections that may be accepted.
#
#       If pptpd is allocating IP addresses (e.g. delegate is not
#       used) then the number of connections is also limited by the
#       remoteip option.  The default is 100.
#connections 100

# TAG: localip
# TAG: remoteip
#    Specifies the local and remote IP address ranges.
#
#    These options are ignored if delegate option is set.
#
#       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 the value of connections,
#       it will start at the beginning of the list and go until it
#       gets 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 10.10.10.254 
remoteip 10.10.10.1-100

对于 vtworay,使用routing字段，针对source ip地址和outboundTag进行路由实现公网SOCKS5出口对内网PPTP的IP
