Thread: Can't bridge wireless and wired interfaces

i have wired , wireless interface on system, , i'd bridge them. need broadcast packets pass between interfaces, because need system on ra0 interface able discover ethernet controller on eth0 interface. after reading online, seems need create bridge between wired , wireless interfaces. when that, wireless interface gets disconnected, , reconnecting not successful. when delete bridge, wireless interface connects immediately.

here network configuration:

code:

eth0      link encap:ethernet  hwaddr d4:85:64:9f:06:9e            inet addr:192.168.2.1  bcast:192.168.2.255  mask:255.255.255.0           inet6 addr: fe80::d685:64ff:fe9f:69e/64 scope:link           broadcast running multicast  mtu:1500  metric:1           rx packets:68682060 errors:0 dropped:0 overruns:0 frame:0           tx packets:32981721 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           rx bytes:73761967812 (73.7 gb)  tx bytes:35411582728 (35.4 gb)           interrupt:42  lo        link encap:local loopback            inet addr:127.0.0.1  mask:255.0.0.0           inet6 addr: ::1/128 scope:host           loopback running  mtu:16436  metric:1           rx packets:146073100 errors:0 dropped:0 overruns:0 frame:0           tx packets:146073100 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:0           rx bytes:141196736823 (141.1 gb)  tx bytes:141196736823 (141.1 gb)  ra0       link encap:ethernet  hwaddr 68:7f:74:7d:06:69            inet addr:192.168.1.224  bcast:192.168.1.255  mask:255.255.255.0           inet6 addr: fe80::6a7f:74ff:fe7d:669/64 scope:link           broadcast running multicast  mtu:1500  metric:1           rx packets:1652713 errors:27 dropped:1 overruns:0 frame:0           tx packets:707681 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           rx bytes:284969278 (284.9 mb)  tx bytes:931799232 (931.7 mb)

to add bridge do

code:

sudo brctl addbr br0 sudo brctl addif br0 eth0 sudo brctl addif br0 ra0

here routing table

code:

kernel ip routing table destination     gateway         genmask         flags metric ref    use iface 192.168.2.0     *               255.255.255.0   u     1      0        0 eth0 192.168.1.0     *               255.255.255.0   u     2      0        0 ra0 link-local      *               255.255.0.0     u     1000   0        0 eth0 default         192.168.1.1     0.0.0.0         ug    0      0        0 ra0

hello


interfaces, need setup routing between interfaces.

difference between bridging , routing bridging, connects 2 interfaces on same subnet,
, both of them on eg 192.168.1.x network, or 192.168.2.x network.

if have interfaces on 2 different interfaces, then have route between 2 networks.

when device on 1 network (ra0) needs contact on eth0 network, device needs know send traffic ra0 eth0 , machine knows how route between two,

doing change approach, if want route between interfaces here detailed guide

also, consider using ics if want share eth0 connection lan devices
