    how to debug an iptable problem?

    I'm an iptables savage - I know just enough to know how thoroughly I could ruin my network configuration, and could use some help. I've tried to wrap my head around iptables several times over the years, and each time stagger away with a headache. I've run into a problem where my AC68U drops...

    Unsure best direction for better logging and securing IoT devices

    I'm into IoT and home automation, but I'm embarrassed to admit I've rather ignored the security aspects of my home network so far. I'd be really grateful for some guidance on the best direction to address this, especially if anyone thinks I might be wasting my time looking into building a NG...

    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...

    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...

    Block All DNS Except

    Is there a way to block all DNS on port 53 except for a specified device? I looked at SkyNET and the Asus WebUI and didn't see anything that really fit the bill. I could really just block 53 across the entire LAN since my DNS server uses 443 for DNS requests. Thanks,
