It's been a while since I last posted. I had a number of problems, most of
which I have
now overcome and I also had a family holiday that got in the way.
In the end, I used dnsmasq to set up the DNS Server on the Pi and I removed all
the
routing that I had set up using iptables commands because nodogsplash covers
everything! In its config file. I was able to allow only those protocols (UDP
and TCP port
53) that were needed to fool the phone into thinking it was on the internet
prior to
authentication and then port 80 and 443 to the Pi (combined Router and
Webserver) to
serve the content. It seems to work pretty well.
I now only have one problem (I hope). Before I started using nodogsplash, many
of the
Visitors were having to accept that our WiFi Access Point had no internet
access before
they could surf to our Home Page. This not very reliable and each version of
Android
behaved differently as related in my message of many months ago. With
nodogsplash,
the Visitor is presented with a Sign-on Page, which he has to read and then
Click
'Continue'. This routes him to the original Home Page and thence to the
content.
On my wife's Moto G6 Plus (Android 8.0), this works well. On my Moto G5 Plus
(Android
7.0), the Home Page is too big and overflows the screen. I suspect this is to
do with the
built-in webserver that nodogsplash uses, because if I surf to the Home Page
with
nodogsplash disabled it works correctly. I used nginx for the original content.
Any suggestions on how I can resolve this?
