Is there no config interface wan6 section in your network config? Make sure you have a big terminal window then it's a simple expression to filter the output to leave DHCPv6 over PPPoE.

I ended up using "option ipv6 1" with a static wan6 interface. If yes, do you use the same version? They offer /56 which is visible in the packet capture, but it doesn't even install that one under ifstatus wan6, let alone adding it under lan interface. but because of the 8byte overhead of pppoe the actual mtu will be 1484. Very clear and simple test. At least this is how I interpret it. report. odhcpd is a daemon for serving and relaying IP management protocols to configure clients and downstream routers.

I currently have DHCPv6 working perfectly like this on my openwrt router, but when trying to test on Windows Server 2012 R2 or Windows Server 2016, it seems I can only create DHCPv6 scopes with a /64 prefix delegation. Default rules apply to interfaces that are not assigned to any zone. Self-registration in the wiki has been disabled. On the OPNsense WAN interface it has a static IPv4 and does DHCPv6 with prefix delegation. Using the basic algorithm: PD Address Space / Number of LAN Ports = block size per port.

I have banip, but it is auto-adding the link local IP of my ISP in the white list. I am under the same impression, that tcpdump will capture traffic on the wire. They suggest the fixed wan interface with a reqaddress: force setting but nothing much else. The DHCP client can then configure an IPv6 address on its LAN interface using the prefix it received. The RG then hands out other /64 in this /60 to dhcpv6 client requests on the LAN, one /64 for each unique IAID. It uses the first /64 from this /60 for the directly connected LAN network (wired and Wi-Fi). However, I think I was getting DHCPv6 responses with option ipv6 1 and option proto dhcpv6 on wan6. I understand there are default wan6 firewall rules. Then you didn't do a clean installation from DD-WRT. This rule is not needed, you are not running a dhcp6 server on the wan interface, are you?

Moreover the only hit is from bogon_6 which doesn't contain the prefix of my provider or any link local addresses. Sections A typical default configuration consists of one dhcp6c section with common settings and one or more interface sections, usually covering the lan and loopback networks. Also make sure that your lan interface has option ip6assign 64 (or a larger prefix size) set to actually redistribute the received prefix downstream. Thanks, I have added the firewall rules shown above as those seemed to be the crucial part which was missing for a dynamic DHCPv6 PPP-based connection. But I think this is not the case, the rules are applied before the network is started. Behavior remains the same, Solicit and Advertise only.
