IPルーティングが機能しない

私の仮想マシンのネットワークブリッジを設定しました。 VMはホストをpingできますが、インターネットでは何もpingできません。私の設定：

# ip route
default via 192.168.1.100 dev wlp3s0 
192.168.1.0/24 dev wlp3s0  proto kernel  scope link  src 192.168.1.106  metric 600 
192.168.10.0/24 dev br0  proto kernel  scope link  src 192.168.10.1 

足

# brctl show br0
bridge name     bridge id               STP enabled     interfaces
br0             8000.7a19fd532c51       no              tap0

br0のTCPDUMP

# tcpdump -i br0
dropped privs to tcpdump
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

wlp3s0のTCPDUMP - br0のパケットがありません。

修正する

systemct の有効化 systemd-networkd と systemct の有効化 iptables を有効にしてブリッジを作成しました。 「手動で」ブリッジを作成すると、すべてがうまく機能します。

/etc/systemd/network/LocalBridge.netdev

[NetDev]
Name=br0
Kind=bridge

/etc/systemd/network/LocalBridge.network

[Match]
Name=br0

[Network]
Address=192.168.10.1/24

/etc/systemd/system/iptables.service.d/10iptables.conf

[Service]
Environment="IPTABLES_INIT=/var/lib/iptables/init-IPv4.rules"
Environment="IP6TABLES_INIT=/var/lib/iptables/init-IPv6.rules"
Environment="COUNTERS=yes"

/var/lib/iptables/init-IPv4.rules 上記の「IP TABLES」セクションと同じです。 /var/lib/iptables/init-IPv6.rules は使用されません。

どんなアイデアがありますか？または、systemdを使用してシステム起動時に初期ブリッジを正しく設定する方法は？
