Finally, the recent commits on master (between the 04-11 and the 04-25) have broken my vbox scenario : virtual box refuses to accessI was also wondering if it would be possible to use several bridges in cascade. If I understand correctly, each Nic session opened on the bridge has an assigned mac address, but would it be feasible to use a single session for a sort of subnetwork?First, when trying to connect a Linux VM through the bridge, it failed to obtain a IP from the DHCP server. I invistigated a little : the Discover packet get through, but the Offer is never transmitted to the client. The config shouldn't be the problem, considering the network worked fine with static IPs. I'm not sure if it is the origin of the issue, but the handling of the offer packet in nic.cc failed to parse the DHCP options (by adding debug prints in the option() function in dhcp.h, I saw that it got the first one right with the correct length 4, but then jumped 6 octet instead for the next option code).Hi,I've been experimenting with the nic_bridge a bit, and I came upon several problems/questions.
