Here's the network I'm trying to setup
192.168.0.3 192.168.0.1 192.168.0.2
OpenBSD | vlan0----><--- vlan0 | FreeBSD | em0 ---><--- em0 | Windows 2000
with net.link.ether.bridge_cfg: vlan0,em0
If I try to ping the FreeBSD machine from OpenBSD, arp requests are sent out, and they
are seen on both of the FreeBSD machine's interfaces. However, no arp response is
generated.
So, I enter in the arp entries myself.
Once I do that, when I again try to ping the FreeBSD host from OpenBSD, the ping
requests are seen on both the FreeBSD interfaces. However, no response is generated.
If I instead try to ping the OpenBSD machine from FreeBSD, the ping requests get to
the OpenBSD machine, and the OpenBSD replies, and both the FreeBSD interfaces receive
the reply, according to tcpdump. However, the ping program does not receive them.
I also tried this setup:
192.168.0.3 192.168.0.1 192.168.0.2
OpenBSD | vlan0----><--- vlan0 | FreeBSD | vlan1 ---><--- vlan0 | Windows 2000
with net.link.ether.bridge_cfg: vlan0,vlan1
And the same problem occurs. I have also tried with different network cards as the
parent interface of vlan0 on FreeBSD (fxp0,dc0).
