Network bridge and broadcast ethernet frames

http://serverfault.com – Let R1 and R2 be two (wireless) routers. Both R1 and R2 have one wired interface eth0 and one wireless interface wlan0. On each router, both interfaces are bridged on br0. So: R1.br0 = R1.eth0 + R1.wlan0 R2.br0 = R2.eth0 + R2.wlan0 Let C1 and C2 be wireless clients connected to R1 and R2 respectively. What will happen exactly when C1 sends a broadcast ethernet frame B, that's supposed to be received by C2 (say, an ARP request for C2's IP address)? My questions: Upon receipt of B by R1, will it send the frame through R1.br0 (therefore sending it to both R1.eth0 and R1.wlan0) or will sen (HowTos)

Hi Guys!

I am beginner with Ubuntu 12.04 and I have the following problem with my network configuration.

Hello,

Lame start, but must appologise for any mistakes I'm prone on making while writing my question - I'm not a native english speaker.

So, here goes ... I'm currently hooked to a BroadBand wireless Router, which supports both wired (ethernet) and wireless connections.

Hi, yesterday I've done a release upgrade from 10.4.1 LTS to 10.10 and I faced the following issues:

1) br0 does not bridge anymore eth0 and wlan0 (I have a DNMA92 wireless card that runs ath9k drivers) at startup even if specified in /etc/network/interfaces:

Code: auto lo iface lo inet loopback pre-up /sbin/iptables-restore < /etc/network/firewall-rules.conf

# The primary network interfac

I have 3 network cards installed in my ubuntu 10.04 server and I want to configure Internet sharing and file sharing on eth1 for wired users and wlan0 for wireless users.

Static ip: eth0: 192.168.1.1 eth1: 10.0.0.15 wlan0: 10.0.0.20

/etc/network/interfaces

# The loopback network interface auto lo iface lo inet loopback

# The primary network interface auto eth0 iface eth0 inet static address 19

Wlan0 Static Ip bridge 16 weeks 4 days ago

EDIT: Even taking br0 out, still cannot get a static IP connection.

I had the following /etc/network/interfaces configuration and it was working

auto lo iface lo inet loopback

auto eth0 iface etho inet manual

allow-hotplug wlan0

auto wlan0 iface wlan0 inet dhcp wpa-ssid "xxxx" wpa-pskl "xxxx"

auto br0 iface br0 inet dhcp bridge_ports wlan0 eth0

I changed the config for wlan0 to the followi

I am trying to configure my ethernet and wireless connections in Xubuntu 12.04 and i tried to set them up by configuring only /etc/networking/interfaces like below.

auto eth0 iface eth0 inet static address 192.168.1.11 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.12 gateway 192.168.1.1 wpa-ssid lausi wpa-psk brezje56

auto wlan0 iface wlan0 inet static

I want to use my desktop with a wired ethernet connection (eth0) to operate my USB Wifi Adapter (wlan0) as a non-adhoc access point (so my android can connect to it).

After MUCH searching, I finally found a method that works with about 95% of what I want.

I modified "/etc/network/interfaces" to contain:

auto lo iface lo inet loopback

auto eth0 iface eth0 inet manual

auto br0 iface br0 i
