I have a captive portal working on a raspberry. My coovachilli is working with an IP and when i connect, i am redirected to login page (http://10.10.10.1:4990...) As i told, it is working fine. But now, i need to put facebook login on this page. To do a facebook login i first need to configure my application on facebook and there i can't set an IP as site URL(facebook don't allow), i must to put a DNS. Then i tried, without success, to configure a internal DNS.
I tried those tutorials here: https://www.howtoforge.com/two_in_one_dns_bind9_views https://www.digitalocean.com/community/tutorials/how-to-configure-bind-as-a-private-network-dns-server-on-ubuntu-16-04
It still not working, if i connect on raspberry and try http://example.com:4990 i get page not found, but with ip it works as always.
I even tried to change /etc/hosts and add 10.10.10.1 example.com, but it works only from inside of raspberry. I knew it, but was desesperated :(
I also put .example.com on coovachilli's allowed domains:
HS_UAMDOMAINS="connect.facebook.net,.facebook.com,.example.com"
[UPDATE] I trespassed this issue by using firebase auth api instead of facebook api. Firebase allows IP, then i was able to put 10.10.10.1 as domain. Facebook login is working now, thanks to firebase, but it would be nice if the url were http://myUrl:4990 instead of http://10.10.10.1:4990
