Hi, I have an embedded system with 2 WLAN and one Ethernet interface and systemd 222 version .
I have a network bridge configured as : /etc/systemd/system/br0.netdev: *[NetDev]* *Name=br0* *Kind=bridge* /etc/systemd/system/br0.network: *[Match]* *Name=br0* *[Network]* *Address=192.168.22.1/24 <http://192.168.22.1/24>* Two wlan interfaces are added tot the bridge: *[Match]* *Name=wlan0* *[Network]* *Bridge=br0* *[Match]* *Name=wlan1* *[Network]* *Bridge=br0* I have the interface connected to a local network: *Name=eth** *[Network]* *DHCP=v4* *IPForward=ipv4* Forwarding is enabled for the eth0 *iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE* Promiscuous mode is also enable for the bridge interface: *ip link set dev br0 promisc on* *I am having the following issue:* Both *wlans* are running in AP mode. *eth0* is connected to the local network that has Internet access. I am connecting from my laptop to one of the AP (wlan1). I can ping the bridge interface, but pinging 8.8.8.8 does not work. With the tcpdump, I can see that the packages are not forwarded from the bridge interface to the *eth0* interface. I have also attached the debug output from the systemd-networkd bridge configuration. One solution that I found to work is as follows: -remove the bridge configuration files br0.netdev and br0.network -manually configure the bridge: 1. brctl addbr br0 2. brctl adif br0 wlan0 3. brctl adif br0 wlan1 4. ifconfig br0 192.168.22.1 I am missing something in the configuration of the bridge for systemd? Thanks, Florin ifconfig output: *br0: flags=4419<UP,BROADCAST,RUNNING,PROMISC,MULTICAST> mtu 1500* * inet 192.168.22.1 netmask 255.255.255.0 broadcast 192.168.22.255* * inet6 fe80::542a:5dff:fe5b:38bc prefixlen 64 scopeid 0x20<link>* * ether 56:2a:5d:5b:38:bc txqueuelen 0 (Ethernet)* systemd-netword debug: *Oct 01 09:32:36 florin-test systemd-networkd[640]: br0: loaded bridgeOct 01 09:32:36 florin-test systemd-networkd[640]: br0: CreatingOct 01 09:32:36 florin-test systemd-networkd[640]: br0: Flags change: +UP +MULTICAST +BROADCAST +PROMISCOct 01 09:32:36 florin-test systemd-networkd[640]: br0: Link 6 addedOct 01 09:32:36 florin-test systemd-networkd[640]: br0: udev initialized linkOct 01 09:32:36 florin-test systemd-networkd[640]: br0: netdev has index 6Oct 01 09:32:36 florin-test systemd-networkd[640]: br0: netdev readyOct 01 09:32:36 florin-test systemd-networkd[640]: br0: Saved original MTU: 1500Oct 01 09:32:36 florin-test systemd-networkd[640]: br0: Adding address: 192.168.22.1/24 <http://192.168.22.1/24> (valid for ever)Oct 01 09:32:36 florin-test systemd-networkd[640]: br0: netdev exists, using existing without changing its parametersOct 01 09:32:36 florin-test systemd-networkd[640]: br0: CreatedOct 01 09:32:36 florin-test systemd-networkd[640]: br0: Link state is up-to-dateOct 01 09:32:36 florin-test kernel: br0: port 1(wlan1) entered forwarding stateOct 01 09:32:36 florin-test kernel: br0: port 1(wlan1) entered forwarding stateOct 01 09:32:36 florin-test kernel: IPv6: ADDRCONF(NETDEV_CHANGE): br0: link becomes readyOct 01 09:32:36 florin-test systemd-networkd[640]: br0 : found matching network '/etc/systemd/network/br0.network'Oct 01 09:32:36 florin-test systemd-networkd[640]: br0: Setting addressesOct 01 09:32:36 florin-test kernel: br0: port 2(wlan0) entered forwarding stateOct 01 09:32:36 florin-test kernel: br0: port 2(wlan0) entered forwarding stateOct 01 09:32:36 florin-test systemd-networkd[640]: wlan1: Enslaving by 'br0'Oct 01 09:32:36 florin-test systemd-networkd[640]: br0: Enslaving link 'wlan1'Oct 01 09:32:36 florin-test systemd-networkd[640]: wlan0: Enslaving by 'br0'Oct 01 09:32:36 florin-test systemd-networkd[640]: br0: Enslaving link 'wlan0'Oct 01 09:32:36 florin-test systemd-networkd[640]: br0: Addresses setOct 01 09:32:36 florin-test systemd-networkd[640]: br0: ConfiguredOct 01 09:32:36 florin-test systemd-networkd[640]: br0: Flags change: +LOWER_UP +RUNNINGOct 01 09:32:36 florin-test systemd-networkd[640]: br0: Gained carrierOct 01 09:32:37 florin-test systemd-networkd[640]: br0: Adding address: fe80::542a:5dff:fe5b:38bc/64 (valid for ever)Oct 01 09:32:51 florin-test kernel: br0: port 1(wlan1) entered forwarding stateOct 01 09:32:51 florin-test kernel: br0: port 2(wlan0) entered forwarding stateOct 01 10:12:13 florin-test dnsmasq-dhcp[520]: DHCPDISCOVER(br0) 192.168.22.83 40:f0:2f:b5:e1:b0Oct 01 10:12:13 florin-test dnsmasq-dhcp[520]: DHCPOFFER(br0) 192.168.22.83 40:f0:2f:b5:e1:b0Oct 01 10:12:13 florin-test dnsmasq-dhcp[520]: DHCPREQUEST(br0) 192.168.22.83 40:f0:2f:b5:e1:b0Oct 01 10:12:13 florin-test dnsmasq-dhcp[520]: DHCPACK(br0) 192.168.22.83 40:f0:2f:b5:e1:b0*
