在/etc/sysctl.conf中添加：

net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-iptables = 1   [root@localhost ~]# cat /etc/sysctl.conf net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-iptables = 1   执行sysctl -p 时出现： [root@localhost ~]# sysctl -p sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-ip6tables: No such file or directory sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-iptables: No such file or directory     解决方法： [root@localhost ~]#
modprobe br_netfilter [root@localhost ~]# ls /proc/sys/net/bridge bridge-nf-call-arptables bridge-nf-filter-pppoe-tagged bridge-nf-call-ip6tables bridge-nf-filter-vlan-tagged bridge-nf-call-iptables bridge-nf-pass-vlan-input-dev   [root@localhost ~]# sysctl -p net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-iptables = 1           —————————————————————————————————————————————————————————————————————————————————————————
