 Subject:  1.2b3 Captive portal: possible MAC pass-through bug
 Date:  Sun, 23 Jan 2005 17:50:22 -0500

I posted earlier about this issue on Dec 12th 2004.

I have a m0n0wall 1.11 box at work and a 1.2b3 box
at home. Both boxes have a wireless AP attached to

The 1.2b3 box's Captive Portal MAC pass-through
doesn't seem to work. I have to add the machine's
IP address in order to allow the traffic.

Here's my client's wireless interface (config'd via DHCP, BTW):

[17:45]jesse@trevarthan:[~/.unison]% ifconfig eth2
eth2      Link encap:Ethernet  HWaddr 00:20:E0:8A:90:61
          inet addr:  Bcast:  Mask:

And here's the relevent section of my 1.2b3 box's config:


If I remove the allowedip rule then trevarthan-wlan cannot ping anything.
Has anyone seen this behavior before? Is it a known bug?
