Hi All!
I am very confused about bridging with MT. I don’t know if I am wrong or the idea 
I want a MT router with one ethernet port and two wireless cards.
The wireless cards should be in a bridge because I want to use dhcp and one IP address domain on the cards (which are in AP mode!)
My problem is that if I put the second wlan card into the bridge, clients’ communication stop (on the first). I realized that if I add the second wlan card then the bridge MAC address changes. Maybe this is relevant.
Here is my conf:
[admin@viztorony] > /interface bridge
[admin@viztorony] interface bridge> print
Flags: X - disabled, R - running
0 R name=“bridge” mtu=1500 arp=enabled mac-address=00:0B:6B:37:ED:0E stp=no
priority=32768 ageing-time=5m forward-delay=15s
garbage-collection-interval=5s hello-time=2s max-message-age=20s
[admin@viztorony] interface bridge> port print
Flags: X - disabled, I - inactive, D - dynamic

0 del bridge 128 10
1 eszak bridge 128 10
[admin@viztorony] interface bridge> /ip address
[admin@viztorony] ip address> print

1 10.4.154.1/24 10.4.154.0 10.4.154.255 bridge
2 10.4.153.1/24 10.4.153.0 10.4.153.255 bridge
3 192.168.4.6/30 192.168.4.4 192.168.4.7 ether1
More interesting that dhcp always work on each wlan cards so clients get IP address and so on.
network:
GW - (ether1)MT (wlan1/wlan2) - clients
Have you got any ideas? Thanks!!
