linux 不同网段pptp服务器的搭建
pptp服务器
内网eth0:192.168.0.10/24 (192.168.0.1是网关)
公网eth1:xxx.xxx.xxx.xxx
用户端拔pptp后分配的ip:192.168.3.0/24
用户未拔pptp前使用的ip:192.168.5.0/24
#yum install ppp libcap-devel libcap
#echo 1 >/proc/sys/net/ipv4/ip_forward
#wget http://nchc.dl.sourceforge.net/project/poptop/pptpd/pptpd-1.3.4/pptpd-1.3.4.tar.gz

localip 客户端要访问的ip (pptp服务器ip )
remoteip 192.168.3.100-200 (用户端将分配的ip)

iptables设置
iptables -A INPUT -j ACCEPT
iptables -A FORWARD -j ACCEPT
iptables -A OUTPUT -j ACCEPT
iptables -A POSTROUTING -j MASQUERADE (关键)
iptables -A POSTROUTING -s 192.168.3.0/24 -j SNAT --to-source 公网ip (关键)
------------------------------------------------
路由设置
eth0设置
IPADDR=192.168.0.10
NETMASK=255.255.255.0 (内网不设网关)
eth1设置
IPADDR=XXX.XXX.XXX.XXX
NETMASK=XXX.XXX.XXX.XXX
GATEWAY=XXX.XXX.XXX.XXX (默认路由)
加路由
route add -net 192.168.5.0/24 gw 192.168.0.1
route add -net 192.168.3.0/24 gw 192.168.0.1
