[Bug 1287157] Re: Bridge only working on second netcard - be2net
The link http://www.ubuntu.com/testing/ is 404.
I can see that there are some errors in my copy-and-paste.
It should read:
dns-search foo.com
dns-nameservers 10.230.80.11 10.230.80.12

Title:
Bridge only working on second netcard - be2net
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
This is reduced bug report for a bug similar to:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1213887
What we have done is to make a simple network and basic installation
af 14.04 daily build from 2014-03-03.
The error is also in 12.04 and later kernels.
If we use the first network card a a bridge:
/etc/network/interfaces:
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto p5p1
iface p5p1 inet manual
auto vlan280
iface vlan280 inet static
address 10.230.80.26
netmask 255.255.255.0
gateway 10.230.80.1
dns-search 10.230.80.11 10.230.80.12
bridge_ports p5p1
bridge_maxwait 0
bridge_fd 0
bridge stp_off
auto p5p2
iface p5p2 inet static
mtu 9000
address 10.230.92.26
network 10.230.92.0
netmask 255.255.255.0
post-up ifconfig p5p2 txqueuelen 10000
You begin to lose pings and the connection to 10.230.80.26 becomes very unstable. The connection to 10.230.92.26 i running without problems all the time.
We get some messages in syslog vlan280: received packet on p5p1 with
own address as source address
If we switch the bridge to the second networkcard the bridge works:
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto p5p2
iface p5p2 inet manual
auto vlan280
iface vlan280 inet static
address 10.230.80.26
netmask 255.255.255.0
gateway 10.230.80.1
dns-search 10.230.80.11 10.230.80.12
bridge_ports p5p2
bridge_maxwait 0
bridge_fd 0
bridge stp_off
auto p5p1
iface p5p1 inet static
mtu 9000
address 10.230.92.26
network 10.230.92.0
netmask 255.255.255.0
post-up ifconfig p5p1 txqueuelen 10000
A normal network setup does not give any problems at all on p5p1
