Allright I'll try to keep it short as title says i'm trying to repeat a fon hotspot to get access to all devices across my house.
I Setted up wlan1 as wan and wlan2 as ap bridge,
setted dhcp client for wlan1, setted addresses and dhcp server for wlan2 and masquerade all traffic through wlan1.
Again when i connect from any other device to my unauthenticated mikrotik, instead of login i get a 404, the same i was getting with the bridge hotspot.
I saw on a dd wrt that fon networks use their own DNS to let client access the login page, that makes sense i guess for the 404 and the user solved it by "Additional DNSMasq Options" in the Services tab of dd wrt, which essentially pushes bt fon DNS to his router clients. I have not figured out since yesterday how to do this in routerOS.
