It's been a few weeks old, but still unanswered. The problem is that as a wifi client only a single MAC address is registered with the AP. The systems behind the bridge have their own MAC addresses, which the AP doesn't know. You either need to setup your wifi with mesh support, run the bridge on the AP instead of the client side, or run dirty tricks with proxy ARP. The best option would be to avoid bridging from wifi completely and route a different net to your vm host or use a cable. -- B.Walter http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm. ___ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
Re: Cannot forward traffic over wlan0 with bhyve
Thanks Trent! I found sometime (leftover time from a full-time work, a newborn and certificate study :/) today to give a try your advise. This is what I ended up with; - assigning an static IP address to tap0 on the host machine - assigning an static IP address to vtnet0 on the guest machine - use pf(4) to forward traffic from tap0 to wlan0 This works, but, as you pointed out, definitely not the optimum way of doing it. I updated the forum entity [1] I created previously, in the hope that that would be useful for some googlers (I have some couple of people having a similar issue) [1] https://forums.freebsd.org/threads/56285/ From: Trent Thompson To: Fehmi Noyan ISI ; FreeBSD virtualization Sent: Friday, May 20, 2016 5:25 PM Subject: Re: Cannot forward traffic over wlan0 with bhyve Fehmi, I noticed in your forum post that you were trying to get a DHCP lease on your bhyve VM.

Cannot forward traffic over wlan0 with bhyve
Hi there, As I mentioned in this forum post [1], I am having issues with getting my FreeBSD-CURRENT VM connected to the Internet via wlan0 interface. I created tap0 and bridge0 interfaces, and edited configuration files to keep changes permanent as suggested by the handbook [2]. I also set the pf rules to enable NAT between tap0 and wlan0 interfaces as described here [3]. When I monitor tap0 and wlan0 interfaces with tcpdump while running "dhclient vtnet0" in the guest OS, I noticed that tap0 forwards packets to wlan0 and wlan0 recevies them (some tcpdump output is in [1]). But nothing happens after this... I also noticed that the pf fails to start with the ruleset given in [3], and having paranhtesis around (bridge0:network) solves the issue, so I filed a bug report for this [4]. I need assistance with my VM internet access and will appreciate you guidance on the matter.
