I can see the packets running as I want over all components.=20 Now my Problem I send a Ping from VBox to PC1 all works fine, while the ping is running I = restart PC1, as suggested ping now fail. After PC1 is up again packet transport should work correctly, but it doesn'= t (exactly some times is ok, some times problem comes after 5th reboot or = so but is coming if I have enough reboots of PC1) . So find the problem I dump the traffic of VLANx, BR0 and TAP0.=20 What I see: @VLANx: arp request and reply=20 @ BR0: arp request and reply @ TAP0: arp request So I think the bridge stop forwarding packets to the TAP device and I don't= understand why.
