bridging wifi and lan

this is the situation

router os V4.5, 4.0 also.
bridge - dhcp server: 192.168.34.0/24 - ports: eth1 eth2 eth3

eth1 - 192.168.22.8 - dhcp client gets address from dhcp on Lan

eth2 - 192.168.34.48 - dhcp client gets address from dhcp on bridge ( internet access for lan )

eth3 - 192.168.34/24 - Wifi AP forwarding to bridge.

eth4 eth5 - PCC, firewall, NAT, internet for Wifi and LAN ( this works)

ip firewall enabled on the bridge for dropping dhcp broadcast on eth1


cannot ping 192.168.22.2 on LAN or anything on LAN using eth1 interface. it times out.

can ping all devices on 192.168.22.0/24 using bridge interface, but only from src address 192.168.34.0

can do ip scan from mikrotik on 192.168.22.0/24 on eth1, but only when eth1 is a dhcp client, else it only finds 192.168.22.8,
and i get timeouts whenever i ping anything. the src address nor interface doesn’t matter.

I would like to have some wifi devices access the LAN through eth1.
when i first add eth1 to the bridge i can access devices on the LAN form the WiFi but doesn’t after about an hour.
any ideas ?
