Hi everybody,
I meet a strange behaviour.
I am running the router Quagga in a Virtualbox 3.0.8 .
I have 'Bridged' my physical interface "eth0" of my computer with Virtualbox.
When Quagga launches OSPFv3 protocol (for IPv6) , I noticed that every OSPFv3 messages (and some ICMPv6 ones) were "doubled" (i mean I received them twice on the physical interface eth0 though the Quagga logs show that it sent only one packet).
With the same Quagga configuration but without using Virtualbox, this behaviour is not happening.
I don't understand why ?
Has anyone already got some packets "doubled" by VirtualBox ?
The most strange thing is coming now: when my eth0 is pluged to my local network (to access the internet for example) I have the packets twice, but when unplugged, I have them only one time... And if I use a virtual interface 'tap' instead of 'eth0' to bridge with virtualbox, I still receive them twice !
Where does this problem come from ? Am I missing a configuration thing for VirtualBox ?
