No internet on the AP (noproxy + captiveflask)

[harames2001]

I have no internet on the Client. (443, see pic.)

• DNS is working (checked)
• Routing to captive portal is working
• IPTables (i could not find any issue)
• DHCP is using another netmask as my ethernet adapter( Could there be any problem with eth=10.152.152.3 netmask 255.255.192.0 ?)
• net.ipv4.ip_forward=1 in /etc/sysctl.conf +reboot.
• Are there any other settings i may miss?
