Use netmakers internal dns server #2463

Closed Ponkhy closed 1 year ago

Ponkhy commented 1 year ago

Hello,

would it be possible to use the dns server of netmaker outside of the internally created network? I would like to create a domain override for my netmaker network in OPNSense, so I can query the netmaker hosts inside of the egress network.

Many thanks for any help!

assuming the docker ip address of the coredns container is 172.18.0.2 add the following two iptables rules on the netmaker server

iptables -t nat -I PREROUTING -p udp --dport 53 -j DNAT --to-destination 172.18.0.2:53
iptables -t nat -I POSTROUTING -j MASQUERADE

then on another host in the network you should be able to run nslookup <hostname>.<networkname> <wireguardip or netmaker server> and get the wg ip address of <hostname>.<networkname>
