As easy as add the eth1 to the bridge I had already created.
Now, openwrt in VM has 2 wifis. One is managed by OpenWrt using the USB Wifi Receiver and the other, using the ASUS AP.
This give me a second SSID managed by AP.
Now I have to improve speed, becaus I'm getting 500mb and I should get almos 1Gb
Regards!
