"Advertise Default Gateway" is enabled in the GUI though. 

When I set the link-local-address/64 under "Advertise Routes" the RA daemon crashes.

I can see multiple IPV6 addresses in the wifi settings (dns,link-local and two addresses within the delegated ipv6-subnet)

When I check the routing via "ip route get" on my android device, I get an: "Network is unrechable" error.

'ip route get' on link-local addresses is working.

ip -6 route show table wlan0 shows:

Yes, the interface does have own IPv6 IP in the delegated. All other devices are working as expected, only my android devices can't establish an IPv6 connection.

This is the radvdump output. Seems ok for me.

General Discussion / Android IPV6 not working - missing gateway

Hey guys,

I can't get IPv6 running on all my android devices. Ive tried almost every Router Advertisement mode. Unmanaged/Managed/Assisted/Stateless. Other devices are working flawlessly.

The android devices are getting an IP address via SLAAC but no route/gateway. When I check the connection via whatismyip.com I get "My Public IPv6: Not Detected"

Any idea how to fix this?

I'm running the latest opnsense version.
