使用路由欺骗思科 VPN

Question

几个月来我一直有同样的问题。我不得不断开连接才能访问互联网。连接后我才能访问公司资源......真麻烦。

我的临时解决方案是在 Debian Linux 下安装 Sonatype Nexus（依赖项的代理）并连接虚拟专用网络。通常你可以用apt-get/yum等来安装它。

当这个解决方案还不够时，我在我的 Windows 机器上安装了 vpnc，并在其上安装了 vpnc-fe http://sourceforge.net/projects/vpncfe/（VPNc Front-End）。

我的配置需要一个名为“Force-NTT”的设置来实现完美的安全。请参阅此主题稍后你需要将以下脚本放入postconnect.bat中：

谢谢你，rodekerken！这是最终结果，无需手动调整即可拆分路线：

REM 
REM Post-Script.bat to take VPNC's Route Table into Windows 7 land. Erases bad route table entries, 
REM extracts gateway, assigned IP, Netmask, and Cisco split route entries and resubmits them to 
REM Windows 7 so the routing all works. Condensed from other entries on the VPNC-FE forae and combined
REM with information gleaned from VPNC client for Linux to find all the passed parameters useful
REM to making this work. Additional by rodekerken noted below, thank you for helping finish it out.
REM
setlocal enabledelayedexpansion
echo.
echo Post-Script Begin
echo.
REM Gather Connection Data
REM 
REM Parameters passed have space at end, see "HELP SET" at Console Prompt for explanation of
REM substring extraction
REM Strip space from TUNDEV, INTERNAL_IP4_ADDRESS, VPNGATEWAY, CISCO_SPLIT_INC
REM This will be broken if VPNC-FE is fixed to not export parameters with the trailing space.

set MyTUNDev=%TUNDEV:~0,-1%
REM By: rodekerken
REM From the top of the router table printout, look for a line like
REM 14...00 ff 5d b0 44 aa ......TAP-Win32 Adapter V9 to find the if number.
REM A way to find out the interface number automatically and extractis this:
for /f "tokens=1 delims=." %%a in ('route print ^|find "TAP-Win32"') do set MyIF=%%a
set MyIP=%INTERNAL_IP4_ADDRESS:~0,-1%
set MyMask=%INTERNAL_IP4_NETMASK:~0,-1%
set MyVPN=%VPNGATEWAY:~0,-1%
REM Number of Routing Table Entries for Split Tunnel
set MyCiscoSplit=%CISCO_SPLIT_INC:~0,-1%
REM Date Time functions
set ANSIDate=%date:~10%%date:~4,2%%date:~7,2%
set StartTime=%time:~0,2%%time:~3,2%%time:~6,2%
REM Display Connection Data
echo Tunnel Device : [%MyTUNDev%]
echo Tunnel IntFace: [%MyIF%]
echo Tunnel IPAddr : [%MyIP%]
echo Tunnel NetMask: [%MyMask%]
echo Tunnel VPN-GW : [%MyVPN%]
echo .
echo Date Connected: [%ANSIDate%]
echo Time Connected: [%StartTime%]
echo .
REM Cisco Routes are 0 index, 6 Routes = 0-5
echo Cisco Split Routes: [%MyCiscoSplit%]
REM Display Bad Route Table
echo.
echo Bad Route Table
route print | find "%MyIP%"

REM Delete Bad Split Route entries and add back with proper Gateway.
REM Extract Cisco routing table information to feed to "ROUTE ADD"
REM Number of entries passed in Array Index CISCO_SPLIT_INC 
REM For x below, value is 0 to CISCO_SPLIT_INC - 1
REM Address is passed in CISCO_SPLIT_INC_x_ADDR
REM NetMask is passed in CISCO_SPLIT_INC_x_MASK
REM
REM By: rodekerken
REM A way to loop and enumerate and evaluate the routes is like this:
set /A MyCiscoSplit-=1
for /L %%i in (0,1,%MyCiscoSplit%) do (
                set SplitAddr=CISCO_SPLIT_INC_%%i_ADDR
                set SplitMask=CISCO_SPLIT_INC_%%i_MASK
        for /f %%a in ('echo !SplitAddr!') do set SplitAddrEval=!%%a!
        for /f %%a in ('echo !SplitMask!') do set SplitMaskEval=!%%a!
        echo Route%%i !SplitAddrEval! !SplitMaskEval!
        route delete !SplitAddrEval! >nul
        route add !SplitAddrEval! mask !SplitMaskEval! %MyVPN% metric 1 if %MyIF% >nul
)
REM Display Corrected Route Table
echo.
echo Corrected Route Table
route print | find "%MyVPN%"
echo.
echo Post-Script End
echo.

我还在“FOR”后添加了以下路线：

route add 1111.120.120.0 mask 255.255.255.0 0.0.0.0 metric 1 if %MyIF%
route add 1111.185.19.0 mask 255.255.255.0 0.0.0.0 metric 1 if %MyIF%
route add 10.0.0.0 mask 255.0.0.0 0.0.0.0 metric 1 if %MyIF%

[请注意，前两条路线的地址不正确/虚假。无论如何你都需要更改它]

为了使我的脚本重复工作，您需要创建一个包含删除路线的“disconnect.bat”：

route delete 1111.120.120.0
route delete 1111.185.19.0
route delete 10.0.0.0
