I have a CentOS server configured as a PPTP VPN Server.
The client is a Windows 7 with "Use default gateway on remote network" in advanced TCP/IPv4 properties enable. He can connect to CentOS without any problem and can access to:
- The Box of his ISP (
- The CentOS server
- The website which is hosted by the server (through
But he canNOT access any other web service (
google.com or 220.127.116.11)
I am a beginner with web servers so I do not know what can cause this problem.
- Note 0 : The Windows 7 user must be able to access the whole internet through the CentOS PPTP proxy.
- Note 1 : With "Use default gateway on remote network" in advanced TCP/IPv4 UNCHECKED it is the same problem
- Note 2 : With "Use default gateway on remote network" in advanced TCP/IPv4 UNCHECKED AND "disable class based route addition" CHECKED the Win 7 can access google but with the ISP IP (no use of the VPN...)
- Note 3 : I have made a
echo 1 > /proc/sys/net/ipv4/ip_forwardand a
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
