Setting up guest WLAN on a dumb AP (Part 2)

Installing and Using OpenWrt
11

I have re-enabled dnsmasq and firewall and now get an IP address. Yeah! Thank you!

I have enabled the Traffic Rules for Guest DHCP and Guest DNS, but the others are disabled for now. I expect that I only need those to further restrict traffic after I can get to the internet.
