Recently , i set hotspot walled garden config to allow specific dst.address can pass through
for the hotspot verification on the another server (btw this server also in this LAN)
i have the very interesting result (BTW all use wireless to connect)
my laptop(windows x86) it's can successfully connect to this server with out any hotspot login

but in mobile devices
the web result is "gateway timeout"

i'm not sure why but when i disable hotspot server everyting is working
