ipip 是IP隧道模組
過程 1314..1. ip tunnel IP隧道配置步驟
server 1
modprobe ipip ip tunnel add mytun mode ipip remote 220.201.35.11 local 211.100.37.167 ttl 255 ifconfig mytun 10.42.1.1 route add -net 10.42.1.0/24 dev mytun
server 2
modprobe ipip ip tunnel add mytun mode ipip remote 211.100.37.167 local 220.201.35.11 ttl 255 ifconfig mytun 10.42.1.2 route add -net 10.42.1.0/24 dev mytun
nat
/sbin/iptables -t nat -A POSTROUTING -s 10.42.1.0/24 -j MASQUERADE /sbin/iptables -t nat -A POSTROUTING -s 211.100.37.0/24 -j MASQUERADE
刪除路由表
route del -net 10.42.1.0/24 dev mytun
修改IP隧道的IP
ifconfig mytun 10.10.10.220 route add -net 10.10.10.0/24 dev mytun
ip 偽裝
/sbin/iptables -t nat -A POSTROUTING -s 10.10.10.0/24 -j MASQUERADE
