Hi all
Some changes in VLAN-related code went into 6.6 and I think some of them
changed the way the parent interface gets into promiscuous mode. Let me
try to explain...
Our ISP provides internet and VoIP over two separate VLANs (100 and 101,
respectively). Our external firewall has two

Everything works great, but the problem is that the host interface needs
to be put into promiscuous mode for the bridged vlan interface to pass
packets to the virtual machine. No packets can be passed to or from the

The interfaces are put into promiscuous mode automatically when
there's something that
Thanks, tcpdump does it alright, but I'd like to have promiscuous mode on
without running tcpdump in the background if possible. (I'll take this as a

an L2 switch in this case.

ifconfig can't be used to set an interface to promiscuous. You can
use something like tcpdump.
Hello all,
I've looked over the ifconfig man page and can't find a way to set a specific
interface to PROMISC mode on 4.4, for example:
vr0: flags=8843 mtu 1500
Here's another example of that this possible:
sis0: flags=8943 mtu 1500
Is there a way to set the flags to PROMISC for an interf
y other way to create a filtering bridge without putting
interfaces into promiscuous mode?
Thanks for any advice, would really appreciate it.

you need promiscuous mode to act as a bridge.
ayer 2?
Is there anyway possible that this is 'legitimate' traffic?
Is there any other way to create a filtering bridge without putting
interfaces into promiscuous mode?
Thanks for any advice, would really appreciate it.

Why would you want to do that manually? Software that needs

Hi,
How to enable and disable the promiscuous mode with OpenBSD 4.3.
I didn't find the -promisc argument in ifconfig.

interfaces in promiscuous mode. Does this make any sense?
If so, is there an ifconfig flag I can use to accomplish this? Or should I
be looking at some other knob to tweak here?

When I start up the 4 instances of snort, the nic (em0) with the ip
address shows up in promiscuous mode, the others do not.
