Title: [SOLVED] IPv6 Clients - Am I missing something?
Post by: bcjenkins on June 02, 2015, 05:18:12 pm
Greetings,

I have an IPv6 address on my WAN (/64) adapter, and managed to get one assigned to my LAN (/128) adapter. My PCs and Mac are NOT receiving an IPv6 address and when executing a ping6 from the LAN interface, I receive a "No route to host" error.

I didn't see anything in the forums on a simple IPv6 setup, is there one?

Provider is TWC in the US.

Have you looked at these? It's hard to troubleshoot for providers, there are a lot of quirks around. :/

Use the following configuration:
for the WAN:
IPv6 Configuration Type:  DHCP6
DHCPv6 Prefix Delegation size:  64
Send IPv6 prefix hint:  Checked

NOTE:  Don't thing TWC cares about the last 2 options

for the LAN:
IPv6 Configuration Type:  Track Interface
Track IPv6 Interface > IPv6 Interface:  WAN

Reboot router.
End.

For me, this allows my router to get a /128 for WAN, create a /64 for LAN, and Dole out IPv6 IPs to clients.

Thank you both for the comments. The issue as it turns out was unrelated to my OpnSense router and was instead related to my Aruba IAP-225 WAP at the house. The Aruba needs to have broadcast-filtering set to "None" for the SSID. (Source (http://community.arubanetworks.com/t5/Aruba-Instant-Cloud-Wi-Fi/Aruba-IAPs-Drop-All-IPv6-Traffic/m-p/228898/)) I was able to isolate when I tested on a wire.

The settings I am using are below. The DNS is being provided by OpenDNS.

WAN Configuration:
IPv6 Configuration Type: DHCP6
DHCPv6 Prefix Delegation size: 56
Send IPv6 prefix hint: Checked

LAN Configuration:
IPv6 Configuration Type: Track Interface
Track IPv6 Interface -> IPv6 Interface: WAN

System -> Settings -> DNS Servers
208.67.222.222 - Set to WAN IPv4
208.67.220.220 - Set to WAN IPv4
2620:0:ccc::2 - Set to WAN IPv6
2620:0:ccd::2 - Set to WAN IPv6

Firewall -> Rules
Add WAN rule to allow IPv6 ICMP echoreq
