RouterOS Virtualization

I have Big problem with “Bridge” in CHR
I find out if there is a difference between bridge MAC address and Interface MAC address
Layer 3 traffic won’t pass through that Bridge

for exp:

 2  RS To G8-2                             ether            1500                  00:50:56:A7:F9:10
 4  R  bridge1                             bridge           1500 65535            00:50:56:A7:F9:10

then i can ping 192.168.68.1 from my clients

 4   192.168.68.1/24    192.168.68.0    bridge1

but when i change bridge mac admin from (00:50:56:A7:F9:10) to 00:50:56:A7:F9:11
i can’t ping 192.168.68.1

first i think my clients arp table cause the problem
but i checked that too
in my clients arp table

 Internet Address      Physical Address      Type
  192.168.68.1          00-50-56-a7-f9-11     dynamic
