编辑/etc/sysctl.conf
把
net.ipv4.ip_forward = 0
改成
net.ipv4.ip_forward = 1
如果此文件中没有这个选项则将其添加上就行。
然后执行 命令：#sysctl -p
使其生效。

[root@IBM-007 sudo]# sysctl -p

net.ipv4.ip_forward = 1

net.ipv4.conf.default.rp_filter = 2

net.ipv4.conf.default.accept_source_route = 0

kernel.sysrq = 0

kernel.core_uses_pid = 1

net.ipv4.tcp_syncookies = 1

kernel.msgmnb = 65536

kernel.msgmax = 65536

kernel.shmmax = 68719476736

kernel.shmall = 4294967296

vm.min_free_kbytes = 65536

kernel.panic_on_oops = 1

kernel.panic = 60

[root@IBM-007 sudo]# 

[root@IBM-007 sudo]# 

[root@IBM-007 sudo]# ll /

[root@IBM-007 sudo]# 
再一次的查看

[root@IBM-007 sudo]# cat /proc/sys/net/ipv4/ip_forward

1

可以发现其原来的0就变成了1.
