General Discussion / Ipv6 not staying blocked
« on: June 21, 2021, 07:32:24 pm »
I have a few IPs I want to limit to my LAN only. First I set up an alias called NoWAN to hold the IPs. I've attached a pic of my rules. These are the first rules in the list. They block inbound and outbuound ipv4 and ipv6 traffic from anywhere except a LAN address. Now here's the weird part. They work fine for both ipv4 and ipv6 when I'm first connected but, after 10 minutes or so ipv6 starts leaking. Here's what I see on reboot or when I cycle the network connections:
After 10 minutes or so I get:
Note that those are ipv6 adresses.
I've tried making separate rules for ipv4 and ipv6 with the same result. I'm not a networking expert and I don't know much about ipv6. So, any help would be appreciated.
Code: [Select]
ping www.google.com
ping: www.google.com: Temporary failure in name resolution
After 10 minutes or so I get:

ping www.google.com
