Posted: Sun Mar 05, 2017 9:10 Post subject: Comcast IPV6 on wndr4300
using router netgear wndr4300 on Firmware: DD-WRT v3.0-r31277 std (02/07/17)
still can't get IPV6 to work, these are my current settings.
ipv6:enabled
ipv6 type : dhcpv6 with prefix delegation
prefix length: 56
static dns 1:2001:558:feed::1
static dns 2:2001:558:feed::2
mtu: 1452
DHCP6s: enabled (didn't make a difference when it was disabled)
RADVD: enabled
these are my results when I run my ipv6 test
Your IPv4 address on the public Internet appears to be 00.00.000.000
Your Internet Service Provider (ISP) appears to be COMCAST-7922 - Comcast Cable Communications, LLC, US
No IPv6 address detected [more info]
Good news! Your current configuration will continue to work as web sites enable IPv6.
You appear to be able to browse the IPv4 Internet only. You will not be able to reach IPv6-only sites.
Your DNS server (possibly run by your ISP) appears to have IPv6 Internet access.
Side Note*** I have two routers both flashed with ddwrt . wn2000rptv2 is on client bridge mode, the wndr4300 is what I'm using to give out my wifi signal and wired connection.
Did you set everthing back like it was when you first flashed router. Then reboot router and modem once you set router like I posted. Also it will take a minute or so to start IPv6 and may have to release and renew ip address or if linux release dhclient. Wan connection type needs to be Automatic configuration dhcp
Ravd enabled
Ravd custom disabled
DHCP server: used domain: LAN&WAN

yeah I did a backup of my settings ,did a 30/30/30 reset. reapplied my previous settings then applied your settings. my internet connection did seem to improve following your settings . but IPV6 test still giving me 0/10

I think your close edited my previous post and added some things

Sorry I didn't catch this before but what is your physical setup when configuring your router. I see you flashed a repeater that is missing WAN port. What modem are you using?
I'm asking because the wn2000rptv2 can still only be used as repeater I would set up modem if using comcast modem/router combo bridge it then wndr4300 router to the settings I gave above once you get a stable connection with IPv6 then set the wn2000rptv2 as repeater.

1. Ignore everything from damatel as this has absolutely no relevance to dhcpv6-pd. Frankly his suggesting that you flush the ipv6 firewall is downright dangerous.
true I'm a novice and hope you get your repeater working as a router. lol above link is Solved but dangerous
ipv6 via 6rd is a transitional technology offered by some ISPs who have not yet enabled native dual stack. Comcast has been offering native ipv6 for years.
FWIW the solution by rkitover can only be applied to 6rd connections with the same prefix size and 0 bit mask length. even then disabling the firewall is unsound etc.
Ok cool. Now I understand why you pm because it's case by case. So is there another way to configure because everything in tutorials tells me nothing and doesn't work. With the 6rd I could not get IPv6 to work unless I added that to the firewall.
I was only asking about the physical setup because of the last line of his original post. And referring to that because I'm bridged from comcast to dd-wrt then using a standard netgear for wifi that will not support dd-wrt.
I will do some more testing of other configurations to see what I can figure out if I hit a wall may I send you a PM?
I don't mind being wrong just explain why then tell me I'm a idiot
. but IPV6 test still giving me 0/10
