Code:
Router Model:Netgear R7800
Firmware Version: DD-WRT v3.0-r39000M kongat (03/02/19)
Kernel Version: Linux 4.9.161 #372 SMP Sat Mar 2 17:16:38 CET 2019 armv7l
Any idea on how to get ipv6 enabled on this router? I have enabled ipv6, copied and pasted googles dns ipv6 addresses into the dns boxes, and enabled radvd.
Yes I have used IPv6 with PD. but I have not tried using dnsmasq because I read somewhere it was no longer needed anymore to do that. _________________ For people who are new to the dd-wrt forums >> http://www.catb.org/~esr/faqs/smart-questions.html#rtfm

I original had my DD-WRT IPv6 setup on my R7000 with the help of R7000 and IPv6 Thread. Making the transition from R7000 Broadcom to R7800 Atheros required small change since ports are labled diiferent...
WAN = vanl2 (R7000) = eth0 (R7800)
LAN = vlan1 (R7000) = eth1 (R7800)
At first it took a some of time to wrap my head with IPv6 plus the way my ISP was implementing IPv6 with work-round. Check out the link I gave. Good luck. _________________ Home Network on Telus 1Gb PureFibre - 10GbE Copper Backbone

I just tried Openwrt on my r7800 and I got an ipv6 address. I did have to add in googles ipv6 dns ip addresses but was able to check out some IPv6 only sites.
it seems as if I can get an ip address from my isp, but no official ipv6 dns addresses from Mediacom.
@malachi @stalonge
I already tried that. does not work unfortunately D:
@mac913
not sure what I am supposed to be looking for in there. am I supposed to copy and paste a script with some edits? _________________ For people who are new to the dd-wrt forums >> http://www.catb.org/~esr/faqs/smart-questions.html#rtfm

Worked for me when I had time Warner and ipv6. Also had to use prefix delegation and google servers. _________________ I am far from a guru, I'm barely a novice.
I checked the status for the wireless adapter on my computer and I see that its getting an ipv6 address and also the google dns addresses but its not showing anything in ipv6 default gateway.
I got it working. But I have only tested on my Thinkpad and no other devices since I was short on time. I will report back after I have done so.
What i did so far to enable ipv6 and radvd. I added ifconfig eth0 promisc and disabled firewall and applied settings and ran command. I restarted my Thinkpad and I am able to access ipv6 only websites.
Back home and ran the test on my main computer. according to the test ran on http://ipv6-test.com/
it says this in the "how can you improve your score?"

Your router or firewall is filtering ICMPv6 messages sent to your computer. An IPv6 host that cannot receive ICMP messages may encounter problems like some web pages loading partially or not at all.
Should i really be concerned? I did know of the existence of IPv6 but this is my first time actually using it. _________________ For people who are new to the dd-wrt forums >> http://www.catb.org/~esr/faqs/smart-questions.html#rtfm

IPv4 used a separate protocol for finding the MAC address belonging to an IPv4 address: ARP. Because it's a separate protocol iptables doesn't affect it.
IPv6 integrated that functionality and doesn't need/use ARP. The function is implemented using ICMPv6 messages. The difference is that ICMPv6 is affected by ip6tables. If you don't allow the right ICMPv6 messages through you're effectively blocking yourself from using the network. You won't be able to find other systems on your LAN (like the default gateway), and others won't find you.
At a minimum you need to accept neighbour solicitation and neighbour advertisement messages. If you use router advertisements to fund the default gateway and/or use address auto-configuration you'll need to accept those as well. And pinging your machine for debugging can be useful as well, so maybe you want to accept the echo-request messages as well.
