sudo modprobe br_netfilter
验证
lsmod | grep br_netfilter

cat > /etc/sysctl.conf << EFO net.ipv4.ip_forward = 1 net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-iptables = 1 EFO
设置rp_filter的值
cat > /etc/sysctl.d/10-network-security.conf << EFO net.ipv4.conf.default.rp_filter=1 net.ipv4.conf.all.rp_filter=1 EFO
生效
sudo sysctl --system
