MK RB751U-2HnD CPE Bridge, can't give IP by Ethernet Ports

Hi

I have a :

Model: MK RB751U-2HnD
Setup as: CPE against AP
Configuration: Bridge
IP Address by DHCP 192.168.1.42/24
Network: 192.168.1.0
Gateway 192.168.1.1 (router)
RouterOS 6.7

MK connects against AP and can ping internet

[admin@MikroTik] /ip firewall nat> /interface wireless export compact
# jan/02/1970 00:32:53 by RouterOS 6.7
# software id = TRY1-06QQ
#
/interface wireless
set [ find default-name=wlan1 ] band=2ghz-b/g/n channel-width=20/40mhz-ht-above \
    disabled=no distance=indoors l2mtu=2290 mode=station-pseudobridge ssid=\
    INTERNET wireless-protocol=nv2-nstreme-802.11
/interface wireless security-profiles
set [ find default=yes ] authentication-types=wpa-psk,wpa2-psk group-ciphers=\
    tkip,aes-ccm mode=dynamic-keys unicast-ciphers=tkip,aes-ccm \
    wpa-pre-shared-key=welcome2internet wpa2-pre-shared-key=welcome2internet

my goal is connect some device (XBOX) to ethernet port of MK and make some setup to let XBOX take and IP address by dhcp. My problem is I don’t know how to setup now MK to let ethernet device to be able to connect against DHCP server.

Actual behavior is that I plug ethernet between xbox and MK and xbox is not able to get an ip of DHCP SERVER.

In Firewall rules I dont have any rule enabled to avoid problems of block ports etc. In NAT Tab there is one rule enabled:

add action=masquerade chain=srcnat comment="default configuration" out-interface=ether1-gateway

In interface list I have

one called brigde2 (R)and then 6 more, 5 ethernet and one wlan1.

Really appreciate any comment or help.

Thanks
