WRT54GL - wifi and 4x lan bridged to wan

[1an]

Hi all,

I have a wzr-hp-g300nh and also a wrt54gl.
wifi encryption on wzr-hp-g300nh is wpa2, but I have 1 device that isn't capable of wpa2 (a PSP, can only manage wpa+tkip). I also am a bit short on wired ports.

I want to achieve the following
1) wzr-hp-g300nh issues ip_addresses, and manages quotas etc for both routers
2) most wifi clients and faster wired devices connect to wzr-hp-g300nh directly
3) slower wired devices and wpa only wifi devices connect to wrt54gl

I think it might be possible to solve both issues by using the wrt54gl as a switch (all 4 ports + wifi clients get their ip_address via the wrt54gl's wan port, which would be connected to a lan port on the wzr-hp-g300nh: second SSID on wrt54gl wifi encrypted using wpa). All ip_addresses would be on single subnet, and wzr-hp-g300nh issues ip_addresses, manages quotas etc

I have found this post on the openwrt forums, explaining how to bridge 2 ports + wifi to wan on the wrt54gl. It is obvious how to make it 3 ports (move ports 1/2/3 from vlan0 to vlan1 in /etc/config/network) but not so obvious to me how to make it 4!

Will this work? Any suggestions, or is there a simpler way?
