Hello DDWRT,

I have my Engenius 5611 radio in bridge mode and would like to limit it's response DHCP broadcasts to the WLAN interface for use in this setup. From what I understand, this is not possible when the eth0 and ath0 (wireless) interfaces are connected to the same bridge (br0).

Consequently, I tried to follow this tutorial (http://www.dd-wrt.com/wiki/index.php/Separate_LAN_and_WLAN) (although I did not enable NAT translation on the WAN interface as recommended to fix a bug, since I don't have the WAN interface enabled) and the DHCP server is working, but I cannot access the other interfaces (192.168.16.1), which I used to be able to access when my radio was configured as a single bridge. My SPI firewall is disabled, is there anything else that I have to do to connect the two bridges? Have I mis-understood the purpose of the tutorial?

Thank you for your time,
Seanny
