I deployed 3 centos 7 vms with vagrant but I am unable or ping VMs on the same virtual box host running on OSX. any idea?

I already enable br\_netfilter and I did disable firewall and SElinux

also did

echo ‘1’ \> /proc/sys/net/bridge/bridge-nf-call-iptables

reboot but cannot ping

any idea?

I am on bridge mode and all have bridge IP. they can all ping the gateway and can access the internet
