if you use lan0 as wan and bridging lan1-3 why not using wan as management-interface with fixed address?
Hello I come back !
I think that’s I have not welding problems. I have try all lan and the wan in the network.

All the lan0-3 have the same mac address ! I was connected in the bpi-r2 by the WiFi and try all the wired port : I my computer I test ping to wan. stop it. And in the bpi-r2, I do :
ifdown wan
ifdown lan0
ifup lan0
I deconnect the wire of wan and put it at lan0 and test ping with lan0.

No problem I think.
DSA-User-ports (wan,lanx) getting mac-address from CPU-port (ethx). Currently i’m testing to set fixed mac (default is random) without compiling full kernel.
You have no more problem with pingdrops?
No problem with this test. But it’s not the config that I need.
You tested each port? If now all it’s ok you can move to your config step by step. But do not bridge wan+lan or ap0 with lan/wan
Before this hollyday, I have tested a bridge with lan0-3 only. It don’t work. I test no bridge (only lan0 zum bispiel) when I can.
I have try to have a DHCP in my bridge :
auto br0
iface br0 inet dhcp
pre-up ip link set $IFACE address 32:D1:55:7D:03:39 up
bridge_ports lan0 lan1 lan2 lan3
bridge_fd 5
bridge_stp no
up /etc/init.d/firewall start
It don’t work. The bridge need have a public address !
i don’t think this is possible, all your clients need a public ip too. why not connect your ISP to wan and your clients to lan-bridge? thats the normal setup and r2 can do what it is designed for…routing 
bridging your lan to public internet is a very bad idea
I think that’s I have do this with the BPI-R2 and ubuntu. The PBI-R2 has work als a swith.
Today I have a little time to test…
I don’t nothing understand. Before the test I have :
auto wan
iface wan inet dhcp
pre-up ip link set $IFACE address 32:D1:55:7D:03:39 up
up /etc/init.d/firewall start
Before today I have never see problem with this. But today I have rbbot my BPI-R2 and after I have this :
--- 192.168.1.10 ping statistics ---

rtt min/avg/max/mdev = 0.347/0.484/0.587/0.044 ms
I have the problem I had with the bridge br0 :I can’t run vi with a big file.
I try it :
auto lan0
iface lan0 inet dhcp
pre-up ip link set $IFACE address 32:D1:55:7D:03:39 up
up /etc/init.d/firewall start
and I have no problem.

111 packets transmitted, 111 received, 0% packet loss, time 748ms
rtt min/avg/max/mdev = 0.349/0.487/0.607/0.052 ms
After this reboot I have a problem with the https server. It answers with https://192.168.1.10, but it don’t answers with a public name (I use ovh for my domaine).
The name is good “ssh mein_mane” is good but it’s redirect to a other computer. When it’s redirect to the BPI-R2, it’s don’t run.
And I don’t see any problem in /var/log.
The problem with https redirection was due to the interfaces file
Now, I test the ping.
Have you a good configuration for a bridge ?

if A pings B (or opposite direction) through bridge, r2 does not touch Traffic, i guess it’s not running over CPU-Port (ethx), means directly in switch from port lanX to lanY

No packet lost…
I remove the mac address of lan and make a new test. The bridge don’t when I remove the mac address of the lan.
I don’t remenber who, but I have see that’s in a bridge the order of the interfaces is important : ascending order of mac address.
It’s not good, it’s only besser.
When it’s only 1 computer in lan0 or lan1 : it’s good. But, When I put 2 computers, it’s not good 
Now I have do a bridge with all lan and wan.
The bridge have a ip from my home network : 192.168.2.1

The BPI-R work all a switch. But, I have a big problem when I ping the BPI-R2 :

rtt min/avg/max/mdev = 11.148/11.611/16.937/0.535 ms
I try with : My PC <->LanX The BPI-R2 brige WAN <->2 swith <-> the box. The https server works when I aks it with a public name (the call come from the box), but the same server don’t answer when I use 192.168.1.10 (the call come from lanX). I reverse the two wire, the public name don’t answer and 192.168.1.10 answer : only “wan” answer.
nb : I have use http://www.fw-web.de/dokuwiki/doku.php?id=en:bpi-r2:debug-uart I think you must indicate how to connect with the wires. I know TX<=>RX, but not everyone knows.
R2 and usb2serial have both tx and rx…tx have to be on rx of the other (sender to receiver).
Can you ping local ip if https does not answer? Maybe it does not listen on all interfaces…netstat -tulpen shows listening ports…https should listen to 0.0.0.0:443
for the https : All the wire’s output are in the bridge. The https answer only when I ask it by the wan.
for the usb2serial : I know, but I thing it must be written on the page.
I have do a switch with all the port : ap0,wan, lan0, lan1, lan2 and lan3. It’s all in my /etc/init.d/wifi.sh.
For ip static :²

then

At the end I do the bridge. I wait that the bridge is up.
And the end for a up by a dhcpd server :
