VPN Server:<\/strong>PPTPD For Linux
\nVPN Client:<\/strong>PPTP Client For Linux
\nConnect\/Disconnect Command:<\/strong>pon \/ poff $Tunnel
\nRequirement:<\/strong>
\nMPPE support in kernel
\n* How to Check:modprobe ppp-compress-18 && echo Success
\n* How to Install:
\na.Prepare the system for kernel package building:
\ngcc bin86 libc6-dev bzip2 kernel-package kernel-patch-mppe
\nb.Install, unpack, and clean the kernel source package
\nmake-kpkg clean
\nc.Copy \/boot\/config* .\/.config
\nd.Build the kernel package:
\nmake-kpkg
\n–added-patches mppe
\n–append-to-version -mppe
\n–config oldconfig
\n[–initrd kernel-image](Not Woody Version)
\ne. When you are prompted for the CONFIG_PPP_MPPE option, type m and press Enter.
\nf. Don’t forget to reboot.
\nServerSide:<\/strong>
\n\/etc\/ppp\/chap-secret for username & password
\n\/etc\/pptpd.conf for remoteip
\nClientSide:<\/strong>
\n\/etc\/ppp\/chap-secret for host & username & password
\n\/etc\/ppp\/peers\/ for tunnel

\nCase Study:<\/strong>
\n202.*.*.200: VPN Server(VPN:192.168.0.1)(Eth0:172.*.17.1)
\n202.*.*.233: VPN Client(VPN:172.*.0.35)(It’s mine:()
\nWhat is interesting:<\/strong>
\nGet blocked without the IP assigned by the DHCP Server
\nSo How to make use of the 172.*.0.35?
\na.Transfer the DHCP information through the VPN Tunnel(Under Study)
\nb.iptables & ‘ip route’:
\niptables -t nat -A PREROUTING -i eth0 -d 172.*.17.1 -j DNAT –to
\n172.*.0.35
\niptables -t nat -A POSTROUTING -s 172.*.0.35 -j SNAT –to
\n172.*.17.1
\n(Client)route add -net 172.*.0.0\/16 dev eth*
