So I translated it. Java code OS: CentOS 6 32bit VPN server: 192.168.18.1 VPN client IP: 192.168.18.2-192.168.18.30 VPN username: flashing Password: wodemima 1. install ppp $ yum install ppp-y www.2cto.com 2. download and install pptpd (the daemon for point-to-point tunneling ). http://poptop.sourceforge.net/yum/stable/packages/ this URL is available for all packages. Note that if there is no error, debian apt can directly install pptpd, so there is no debian package.
Java code $ cd/usr/local/src $ wget http://poptop.sourceforge.net/yum/stable/packages/pptpd-1.3.4-2.el6.x86_64.rpm $ Rpm-Uhv pptpd-1.3.4-2.el6.x86_64.rpm 32-bit Download wget http://poptop.sourceforge.net/yum/stable/packages/pptpd-1.3.4-2.el6.i686.rpm I didn't even have wget in the newly installed system. I had to install wget in yum first ,?? /Div> 3. modify/etc/pptpd. conf www.2cto.com localip 192.168.18.1remoteip 192.168.18.2-30localip is the ip address of the ppp virtual intranet gateway, and remoteip is the ip address segment. for example, 2-30 allows 192.168.18.2-192.168.18.30, after I dial up, the IP address allocated for the vpn connection is 192.168.18.30 4. modify/etc/ppp/options.ppt pdrequire-mschap-v2require-mppe-128ms-dns 8.8.8.8 this is nothing to change, mainly add dns address 5. modify/etc/ppp/chap-secrets. the username and password format are as follows: [username] [space] [server] [space] [password] [space] [IP addresses] flashing pptpd woshimima * www.2cto.com 6. modify/etc/sysctl. the following sections of conf are the parts where the iptables package forwards the net. ipv4.ip _ forward = 1 7. make change 6 Take Effect $ sysctl-p 8. open the nat $ iptables-t nat-a postrouting-o eth0-j MASQUERADE $ service iptables save $ service iptables restart
Edit/etc/sysconfig/iptables. Note the following two points: a adds A line-a input-p tcp-m state -- state NEW-m tcp -- dport 1723-j ACCEPT because the default vpn is access B of port 1723 #-a FORWARD-j REJECT -- reject-with icmp-host-prohibited must be commented out, you can also change the ip address range 192.168.18 to forward. Otherwise, you cannot access the Internet through the vpn. 9. pptpd is made into a service, and then restarted, over. $ chkconfig pptpd on $ init 6 www.2cto.com 10. finally, create a vpn connection for windows or clients and fill in the user name and password you just entered.
