IPV6 DHCPv6 issues

2021-10-20 23:06:18

Model: OC200

Hardware Version: V1

Firmware Version: 4.4.4

I'm running a RT605 on an Omada OC200

I'm having issues getting IPV6 to work properly.

I have the wan side setup to Dynamic IP (SLACC/DHCPv6) which appears to be working fine as the router claims it's online on both IPV4 and IPV6

Now If I request Prefix Delegations from my ISP (xfinity) and I set it to 60 I only get one set from them not 16.

I did do a quick test on my one vlan using slacc + stateless dhcp and devices under that vlan did get connection to the internet under ipv6. However I want all my vlans to have access to IPV6 and I would more prefer them to be DHCPv6 where I have more control to their IPV6 address.

If I set the lan to DHCPv6 my devices will get their proper addresses for IPV6 however they won't have internet access.

What am I missing to make DHCPv6 work so that it will pass traffic from the Lan devices up to the WAN via IPV6 where I'm not forced to use slacc just to make it work.

Bumping this just to see if anybody has figured out a solution or if there is a work around like IPV6 NPT or some other potential solution. I'm still only getting a /64 delegation from xfinity and not a /60. I saw with the PF sense that it suggest changing the DUID, is there a way to change the DUID on the rt605 router?

@hightechredneck I have discovered a bug which may be related to your issue.

I have an EAP650 access point that is dropping all DHCPv6 ADVERTISE and REPLY packets. It's behaving as if the "Legal DHCP servers" option were enabled, however this option is not enabled for any of my networks. I have an older EAP245 AP in the same network which behaves correctly and does not drop DHCPv6 packets, so I'm almost certain this is a bug in the EAP650 firmware (possibly for other newer APs too).
