Hello, i have a problem to configure a dhcp server with bridge port.

I have an rb411 with two radio module: wlan1 (2.4 ghz) and wlan2 (5 ghz)
and one ethernet port

ethernet port and wlan2 are bidged with ip 192.168.1.x for internal network
i configure ether1 with another ip address (10.0.0.x) for internet connection (gateway 10.0.0.254)
I would like activate a wlan1 dhcp server (ip class 10.10.10.x) and redirect the client to the internet gateway 10.0.0.254. This configuration doesn't work..if i disable bridge port (wlan2 - ether1) configuration work.

Any suggestion?

Thanks
