    TP-Link home routers: any support for IPv6 firewall?

    Do any TP-Link home wifi routers have support for an IPv6 firewall (meaning the ability to block unsolicited inbound IPv6 traffic, except for stuff that is required by IPv6 itself, e.g. ICMPv6, etc)? I know the Archer C7 doesn't (via my own testing). How about the Archer A20? I've asked...

    How is IPv6 DNS server determined by a client?

    I have a problem with IPv6 DNS: I am using Comcast via an ASUS RT-AC86U router with IPv6 enabled. On my LAN I have a Pi-hole on a Raspberry Pi 3B+ and want all DNS requests to go to it either by its IPv4 or IPv6 address. The router WAN IPv4 DNS settings are manually configured for server 1 and 2...

    IPv6 firewall fails to function.

    RT-AC56R 384.6 (latest for this model at time of posting) IPv6 firewall on/off switch seems to generate a complete blockage in the "on" position and had none of the rules entered in the GUI. In the "off" position it drops bad packets, but otherwise allows nearly everything through. Anyone have...

    Can I Block Specific Devices from getting IPv6 Address?

    Running latest Asuswrt-Merlin 384.12 on an RT-AC86U. My ISP has enabled experimental IPv6 support on their infrastructure and I'd like to have a play with it on my network, mostly as a learning exercise at this point. I got it working fine using "Native" mode and with DHCP-PD "Enabled". Is...

    ipv6 and ATT WiFi Calling not working

    Every new ASUS firmware upgrade is an adventure. I am running a somewhat standard setup. 3 nodes (mesh), all RT-AC68U - one node hard wired and one node wireless. After the latest firmware update (3.0.0.4.384_45717) I noticed my ATT Wifi Calling wasn't working anymore. After a little...

    IPv6 keep disabled when WAN type is set to "USB"

    I am using Android Phone as USB modem to access Internet. WAN type is set to "USB". On my previous router, Asus RT-AC56U, IPv6 worked fine. I set IPv6 "Connection type" to "Passthrough", and the devices connected to the router could get the IPv6 prefix correctly and access Internet through...

    RT-AX88U IPv6 Default GW Missing

    Hi all I have used different models running Asuswrt-Merlin (legacy) for several years with the same ISP (Init7) and IPv6 has always worked very well. Since upgrading to an RT-AX88U (the first time running a NG FW), the router no longer detects the default GW: This obviously breaks all IPv6...

    LAN IPv6 setting on my R7800

    Hi, Since my ISP now has IPv6 support implemented I thought I would check it out on my R7800. I have IPv6 set up and working. but there's one setting I wonder about. What will the practical difference be between using "Use DHCP Server" and "Auto Config" for the "LAN Setup"? I have tried both...

    Ac68u, openvpn-server blocks all WAN traffic on reboot

    Hi I have configured open-vpn and it generally works. But only until I reboot. As I think this might be related to having disabled IPV6 and the router while booting falling back to ipv6. Then all traffic to WAN is blocked. Jan 27 10:38:21 ovpn-server1[737]: OpenVPN 2.4.6 arm-unknown-linux-gnu...

    WAN IPv6 gateway problem [fix]

    As mentioned in the post below, my WAN IPv6 gateway was not set with Native with DHCP-PD enabled. I was able to interim fix this issue by adding a WAN-startup-script, to manually add the gateway. #!/bin/sh ip route add default via fe80::1 dev eth0 @RMerlin, the nvram variable...

    OpenVPN and IPv6 (under CGNAT)

    Hi, My current ISP (hyperoptic in the UK) has implemented CGNAT, so I can't access my router from outside my home network. I thought about setting up the OpenVPN server, and access to it through IPv6 (considering that the ISP I'm under when I'm away from home supports it), but I'm quite lost...

    [IPv6 6rd Tunnel] Subnetting IPv6 the non-standard way

    My ISP is Telia, and I'm using these settings in IPv6: I have a /56 prefix, so I would want to give one subnet of it to Docker containers running on a virtual machine and seperate subnet for the rest of my LAN. How would I get this done on the router? I would rather use the router for this...

    [Solved] IPv6 on my R7800

    Hi, I've been running iPv6 without problems on my R7800 without problems. I would now like to switch to my prefered DNS provider (Quad9) but I can't figure out how to enter the addresses on the R7800. The addresses are: 2620:fe::fe and 2620:fe::9 On the R7800 there are the 8 alphanumeric...

    Slow IPv6 DNS lookups on a R7800 when IPv6 DNS servers are set manually

    Hi, I am not sure whether this post belongs in a Voxel firmware thread or here as a general R7800 question since I use Voxel firmware on my R7800. Anyway If I use manual set ipV6 DNS servers like Cloudflare after a while it takes up to 30 seconds to resolve and get to any web site or service...

    Asus RT-AC87U (WRT-Merlin) and IPv6

    Hello, Today I have contacted by my ISP to propose a new broadband connection. I currently have a public IPv4 line connected to my ISP modem which connects to my ASUS RT-AC87U with AsusWRT-Merlin 384.7. Behind the router I have a couple of QNAP NASes and one Vu+ decoder that I can access...

    DNSfilter and Hurricane Electric Tunnel

    Recently, I started using the newly added Quad9 dnsfilter along with the dnssec setting. Works nicely, thanks. I changed the dns setting in my Hurricane Electric tunnel to the DNS ipv6 servers, and it no longer works. Tried setting the dns settings on the tunnel page back to HE dns, but it still...

    I see this in my log, and it happens very frequently. Do I even need IPv6 enabled? I saw in another thread from john9527's fork to select Yes for the setting: Prefix delegation requires address request. I did that but still get the log output. I have Xfinity in the East Bay California, USA...

    384.7 IPV6 Stateful Generates Logged Errors, Stateless Does Not

    I enable stateful vs stateless in order to have routable IPV6 addresses. After doing that, and a quick restart of the router, I checked that the target devices had drawn a routable IPV6 address and then made the proper IPV6 firewall entries. Shortly after, I noticed the log entries shown below...
