Hi,
I am using a RUTX50 router in my camper. To connect to my homelab I am using Zerotier. In my homelab I have a Zerotier bridge.
Please see this picture for an network overview:
On IP level the connection is working fine. From the camper I can access any IP within 10.0.0.0/8.
In my homelab I am using the domain kletzin.de with several subdomains for the different services. To access these services with FQDN I would like to use my DNS Server to resolve *.kletzin.de FQDNs by using DNS Server 10.10.31.18. I tried two different methods:
Define DNS service in Zerotier:
When I use my mobile device it recognizes the DNS config within Zerotier, I can resolve against 10.10.31.18. From the RUTX50 it doesn’t work - even if I activate User DNS in Zerotier config.
Any idea why the RUTX50 doesn’t recognize the Zerotier DNS server?
Use DNS forwarding in RUTX50
In the RUTX I have configured the DNS forwarding. That doesn’t work.
Configuration to forward to DNS in my homelab:
Result in CLI:
root@KASTEN-ON-TOUR:~# nslookup grafana.kletzin.de
Server: 127.0.0.1
Address: 127.0.0.1#53
*** Can't find grafana.kletzin.de: No answer
*** Can't find grafana.kletzin.de: No answer
To check if the DNS resolution is working I tried to resolve explicitly against 10.10.31.18. That ist working:
root@KASTEN-ON-TOUR:~# nslookup grafana.kletzin.de 10.10.31.18
Server: 10.10.31.18
Address: 10.10.31.18#53
Name: grafana.kletzin.de
Address 1: 10.10.31.13
*** Can’t find grafana.kletzin.de: No answer
Any idea why the DNS forwarding is not working?
Thanks
Michael
