Originally created by @sahara101 on GitHub (Jul 31, 2024).

Hello!

I have an exit node defined. Is there a way to use it only for the internet traffic and block the LAN access to it? I tried with an access control where I blocked my DNS IP, 192.168.1.172/32, but it still works. My iPhone and the exit node are both in a group called exit. I added DNS for it as 8.8.8.8.
Thanks!

Currently, there's nothing built-in, but you could add custom iptables/nftables rules to block traffic from the netbird interface that targets any of your LAN networks
