Did you tried to check the option 'Shared Physical Network' under System:
Advanced functions?

Hi all,
I'm running PFSense 1.0.1 with three interfaces: WAN, LAN and then OPT1
acting as a bridged interface with the WAN. Our DSL provider gives us a
/29 on the LAN port of their router and I use the first available IP for
the PFSense WAN IP (which is also used for NAT on the LAN) and the
remainder of the /29 bridges to OPT1.
On the boxes connected to the bridge interface I periodically get the
following messages in the logs:
Jan 30 23:45:54 devel2 /kernel: arp: 74.x.x.26 moved from
00:50:ba:52:00:95 to 00:b0:d0:b6:94:3d on fxp0
Jan 30 23:47:21 devel2 /kernel: arp: 74.x.x.26 moved from
00:b0:d0:b6:94:3d to 00:50:ba:52:00:95 on fxp0
Jan 31 00:05:48 devel2 /kernel: arp: 74.x.x.26 moved from
00:50:ba:52:00:95 to 00:b0:d0:b6:94:3d on fxp0
The two MAC addresses in question are the WAN and OPT1 interfaces. I've
seen some discussion of this on the freebsd-stable list, but no real
good
info. WAN is an rl card, OPT1 is an xl if that matters.
Any ideas why the bridged hosts occasionally see the "invisible" MAC
address of the OPT1 interface?
It thinks there is some kind of loop somewhere. While I cannot
certify your working environment without a lot more questions and
answers which is beyond this mailing list I can tell you how to squash
this message... System -> Advanced -> Shared Physical Network
Sorry for returning to this so late... I think last time I got lost on a
tangent of trying to find software to help draw ascii network diagrams and
never came back... :)
In short, here's the network. Pretty simple, no loops, very common setup
for a US SDSL or routed ADSL customer with ISP-provided CPE:
| ADSL w/routed /29
|
+---|----+
| router |
+--------+
| 74.x.x.25 (network is 74.x.x.24/29)
|
|
| WAN 74.x.x.26 - 00:50:ba:52:00:95
+---\----+
|pfsense |
+-/-----\+
LAN / \ OPT1 (bridged w/WAN, ie: 74.x.x.24/29
(192.168.0.1/24 - nat) / \ 00:b0:d0:b6:94:3d)
+------+ +-'----+
|switch| |switch|
+------+ +------+
| | | |
workstations at | | | |
192.168.0.2-20 | | +--+ +--+
+--+ +--+ | | | |
| | | | | | | | servers at 74.x.x.27, 74.x.x.28
| | | | | | | | (these report that 74.x.x.26
| | | | | | | | is "moving")
+--+ +--+ +--+ +--+
Does that clarify things?
There is NO physical connection between the OPT1 and WAN networks, hence
no loop.
Thanks,
Charles
