I have debian server with a bridge interface. Everything is fine in terms of configuration, however I can't ping default gateway as well as internet (obviously). Any idea why?root@UKLNDLABPI:~# route -nKernel IP routing tableDestination     Gateway         Genmask         Flags Metric Ref    Use Iface0.0.0.0         192.168.1.1     0.0.0.0         UG    0      0        0 br0169.254.0.0     0.0.0.0         255.255.0.0     U     202    0        0 eth0169.254.0.0     0.0.0.0         255.255.0.0     U     303    0        0 wlan0192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 br0root@UKLNDLABPI:~# brctl showbridge name bridge id       STP enabled interfacesbr0     8000.b827eb20770c   no      eth0                            wlan0root@UKLNDLABPI:~# ifconfig br0       Link encap:Ethernet  HWaddr b8:27:eb:20:77:0c            inet addr:192.168.1.3  Bcast:192.168.1.255  Mask:255.255.255.0          inet6 addr: fe80::ba27:ebff:fe20:770c/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:1577 errors:0 dropped:0 overruns:0 frame:0          TX packets:777 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:175454 (171.3 KiB)  TX bytes:74358 (72.6 KiB)eth0      Link encap:Ethernet  HWaddr b8:27:eb:20:77:0c            inet addr:169.254.91.34  Bcast:169.254.255.255  Mask:255.255.0.0          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:190 errors:0 dropped:0 overruns:0 frame:0          TX packets:79 errors:293 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:8740 (8.5 KiB)  TX bytes:13238 (12.9 KiB)lo        Link encap:Local Loopback            inet addr:127.0.0.1  Mask:255.0.0.0          inet6 addr: ::1/128 Scope:Host          UP LOOPBACK RUNNING  MTU:65536  Metric:1          RX packets:548 errors:0 dropped:0 overruns:0 frame:0          TX packets:548 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1           RX bytes:50801 (49.6 KiB)  TX bytes:50801 (49.6 KiB)wlan0     Link encap:Ethernet  HWaddr b8:27:eb:75:22:59            inet addr:169.254.180.198  Bcast:169.254.255.255  Mask:255.255.0.0          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:1403 errors:0 dropped:13 overruns:0 frame:0          TX packets:939 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:169864 (165.8 KiB)  TX bytes:104371 (101.9 KiB)root@UKLNDLABPI:~# cat /etc/network/interfacesauto loiface lo inet loopbackiface eth0 inet manualallow-hotplug wlan0iface wlan0 inet manual#   wpa-conf /etc/wpa_supplicant/wpa_supplicant.confauto br0iface br0 inet static     address 192.168.1.3    netmask 255.255.255.0    gateway 192.168.1.1    bridge_ports eth0 wlan0root@UKLNDLABPI:~# ping 192.168.1.1PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.From 192.168.1.3 icmp_seq=1 Destination Host UnreachableFrom 192.168.1.3 icmp_seq=2 Destination Host Unreachable
