[root@computer ~]# ls /proc/sys/net/bridge/
bridge-nf-call-arptables bridge-nf-call-iptables bridge-nf-filter-vlan-tagged
bridge-nf-call-ip6tables bridge-nf-filter-pppoe-tagged bridge-nf-pass-vlan-input-dev
[root@computer ~]# sysctl -p
[root@computer ~]# sysctl net.bridge.bridge-nf-call-ip6tables
net.bridge.bridge-nf-call-ip6tables = 1
[root@computer ~]# sysctl net.bridge.bridge-nf-call-iptables
