I am setting up a bridg for use wit a UMTS USB modem (ubuntu 9.04)
I want the following solution:
roaming gprs modem | <=USB0=> | ppp0 ubuntu server br0 | eth0
I have testet with this solution (/etc/network/interfaces) without any luck.
iface lo inet loopback
# Configure br0 using ifupdown with dhcp and add eth0 to the bridge
iface br0 inet dhcp
# udev calls ifupdown for usb0 when it is created and destroyed. See /etc/udev/rules.d/85-ifupdown.rules
# Tell ifupdown not to assign an IP address and add it to the bridge.
iface usb0 inet manual
up ifconfig $IFACE 0.0.0.0 up
post-up brctl addif br0 usb0
> brctl show shows ony the one endpoint (eth0)
Have anyone a pointer or a solution to this?
