转载于 centos7添加bridge-nf-call-ip6tables出现No such file or directory
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
