Why can't I see the network behind OpenVPN?

Question

openvpn

Good time of the day. Came with the following problem: The
task is to provide access to network folders on different machines of the internal network via OpenVPN.
To do this, I raised a virtual machine with a clean Ubuntu Server 16.04.3
Internal network has an address space of 10.0.0.0 255.255.255.0
Installed and configured OpenVPN in bridge mode. The client connects (window), can ping the VPN server, but does not see the network behind the server.
Bridge configuration in /etc/network/interfaces

auto eth0
iface eth0 inet manual
up ip link set $IFACE up promisc on
auto br0
iface br0 inet static
address 10.0.0.10
netmask 255.255.255.0
bridge_ports eth0

Traffic inside the bridge

iptables -A FORWARD -m physdev --physdev-is-bridged -j ACCEPT

Server config

port 3392
proto tcp
dev tap
up "/etc/openvpn/up.sh br0 eth0"
ca ca.crt
cert server.crt
key server.key
dh dh2048.pem

Tell me how to open full access to the internal network?
