DNS Resolution on linux Hosts

[farru_19]

Everything related to domain name resolution works fine in mobile and windows client where I have the option to set the Zerotier IP as my DNS server. But I don’t seem to find any ways to resolve domains when connected via linux machines.

I’m facing the same issues mentioned below :

Setting up DNS on ZT network

I’m making a webserver, and I can’t open ports, so I’m falling back to ZT. ZeroTier works, as expected. I can connect to the other machines on the network, and I can connect to the server via its ZT IP. Well, I want to give it a name, so I can type that instead of the IP. I went into the server’s /etc/hosts file (it’s running Arch Linux) and added one line, just to test: testdomain.com 127.0.0.1 As expected, from the server itself I can type ping testdomain.com and it gets indeed redirected t…

Was this issue resolved? Are there any work arounds?

For proper local domain name DNS resolution when using zerotier in Linux, I added these firewall rules and set my Pihole Zerotier IP (192.168.195.x) as DNS server for specific interface (eth0 or wlan0).

Add these rules and save iptables.
sudo iptables -A INPUT -i zt0-p udp -m udp --dport 53 -j ACCEPT
sudo iptables -A INPUT -i zt0 -p tcp -m tcp --dport 53 -j ACCEPT
sudo iptables -A INPUT -i zt0 -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT

This worked for me in resolving local domain name (service.home.lan). I did not setup any DNS server in zerotier central or download and install zeronsd.
