Container veth91 ping problem from LAN

Hi
I have problem with new container
from router I have a ping to container IP and container IP bridge
from lan network have a ping only to IP bridge, can’t ping container interface IP

/interface/bridge/add name=dockers
/ip/address/add address=172.20.0.254/24 interface=dockers

/interface/veth/add name=veth91 address=172.20.0.91/24 gateway=172.20.0.254
/interface/bridge/port add bridge=dockers interface=veth91

From LAN PC have a ping to 172.20.0.254, but not to 172.20.0.91 ?
