DHCP problems



  • Hi, I have successfully connected my pfSense box with IPv6 using an HE tunnel. Everything seems to be working good as I can successfully ping any ipv6 enabled site I have tried from my pfSense box.

    The problem I'm facing now is on my LAN, as I cannot make the DHCP6 + RA to work successfully, because I cannot make it lease ip addresses to my LAN clients, except for an iPad that it apparently received an IPv6 address, but when I checked it, it only have the address for the a DNS server, but no ip address for itself, and obviously the test-ipv6.com check cannot find an IPv6 address assigned either.

    I have some Win10 notebooks, Android 6 phones, RPis, Xbox, iPad, SmartTV, Chromecast, etc. I can understand that not every device will automatically work, but none of them?

    These are my config snapshots for DHCPv6 Server and Router Advertisements. Ileft almos everything as it is and just configured the router mode and DHCP range of addresses to lease.

    Am I missing something?, are they wrong?

    Thanks,
    Pablo






  • I suggest to set radvd to Unmanaged instead of Managed in order for your clients to get stateless IP addresses. This should work.
    As far as I can tell DHCPv6 is no really ready for usage mainly because the different client implementations on the different OSes don't work really well.

    Thanks, I've done exactly that and created some overrides for the DNS Resolver just for the machines I have to access remotely so I can access them by names.
