Why is the bridge not working?

Hello.
Perhaps there is something I don't know.
There are 2 NICs on the server.
em1 is connected directly to the provider.
em4 on the local network.
Set up a br0 bridge and bind em4 to it.
em4

[[email protected] network-scripts]# cat ifcfg-em4
ONBOOT=yes
BRIDGE=br0
TYPE=Ethernet
DEVICE=em4
NAME="System em4"
UUID=17b7e246-327c-76fb-6648-b59ca1bdc81e

br0
[[email protected] network-scripts]# cat ifcfg-br0
DEVICE=br0
TYPE=Bridge
ONBOOT=yes
BOOTPROTO=static
IPADDR=172.16.100.149
NETMASK=255.255.255.0
GATEWAY=172.16.100.10
DNS1=8.8.8.8
DNS2=77.88.8.8
STP=no
PROXY_METHOD=none
BROWSER_ONLY=no
PREFIX=24
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=no
NAME="Bridge br0"
UUID=d2d68553-f97e-7549-7a26-b34a26f29318
ZONE=internal

As you can see, the br0 gateway goes to the router (172.16.100.10), which distributes the Internet.
I'm doing a ping

That is, everything is ok.
