Adding a second ip address to the BR0 interface

[Ronv42]

I want to add a second IP address to my AC87R to host another web server on port 80. I am concerned that the built in web ui will bind port 80 also to the new address. Has anyone else done this? Here is the command I plan to use:

ifconfig -a br0:0 192.168.x.x 255.255.255.0

And then add it to one of the startup scripts.
