bridging and tunneling not working ..[SOLVED]

[upengan78]

Hi,

I have eth0 as primary interface. I want my virtual box (windows ) to use vbox0 interface on gentoo. Also I would like windows in virtualbox receive DHCP IP after configuring virtual box windows to use vbox0

following is /etc/conf.d/net

config_br0=( "dhcp" )
config_eth0=( "null" )
config_vbox0=( "null" )
tuntap_vbox0="tap"
dhcpcd_br0="-t 20"
bridge_br0="eth0"
depend_br0()
{
need net.eth0
need net.vbox0
}
brctl_br0=( "setfd 0" "sethello 0" "stp on" )

for some reason this set up is not working, br0 never gets an IP from dhcp server as it should.

I have the links in /etc/init.d for net.eth0/net.vbox0/net.br0 poiniting to net.lo and added for default run-level.

am I missing something ?

Thanks

I have mine working. Here is my /etc/conf.d/net

Code: Select all

config_eth0=( "null" )
config_vbox0=( "null" )
tuntap_vbox0="tap"
dhcp_eth0="nodns"
dhcp_br0="nodns"
dhcp_vbox0="nodns"
bridge_br0="eth0 vbox0"
config_br0=( "dhcp" )
routes_br0=( "default via 192.168.0.1" )
depend_br0() {
        need net.eth0
        need net.vbox0
        }
brctl_br0=( "setfd 0" )

I also have to run

Code: Select all

tunctl -t  vbox0 -u <user>

before I launch virtualbox.

if I look at ifconfig, it shows:

Code: Select all

All the networking works from the windows in virtualbox.

Thanks for complete config, I will check here and let you know !

Thanks again !

I tried your config for /etc/conf.d/net and br0 did receive an IP address from dhcp server but while I saw it receving an address and using an IP as a gateway I also did see following line while system is booting..

Code: Select all

RNETLINK ANSWERS - FILE EXISTS  [!!]

is it related ? please advise

Thanks much.

[jtaylor72]

It is from this line:

Code: Select all

routes_br0=( "default via 192.168.0.1" ) 

I was actually getting a similar error and not noticing it:

Code: Select all

SIOCADDRT: File exists

I removed the routes line and restarted the network and they all still worked just fine.
