Resolve DNS names

[rcrivelli]

Hi

The VPN connection is working.
I can ping IP Addresses in the remote network. e.g. 10.100.0.55
But when i thy to ping the hostname e.g. host1.domain.local the name is resolves to the ip address 127.0.0.1.
i've tested it on my machine and directly on the UDM-PRO.

Via DHCP i've set these DNS servers:

• IP UDM-PRO
• IP of remote DNS Server in the VPN remote network

Do i've forgot anything?

Thx.

user@Users-MBP ~ % traceroute host1.domain.local
traceroute to host1.domain.local (127.0.0.1), 64 hops max, 52 byte packets
1 localhost (127.0.0.1) 0.485 ms 0.058 ms 0.046 ms

And now the traceroute to the IP of this host:

user@Users-MBP ~ % traceroute 10.100.0.55
traceroute to 10.100.0.55 (10.100.0.55), 64 hops max, 52 byte packets
1 unifi (192.168.1.1) 1.246 ms 0.845 ms 0.911 ms
2 172.172.33.15 (172.172.33.15) 17.696 ms 17.424 ms 20.025 ms
3 10.100.0.55 (10.100.0.55) 18.970 ms * 19.770 ms

So you're saying DNS isn't working, is that the problem? IDK what could be done about the DNS, I believe it's being pushed by my OpenVPN connection but I'm not utilizing it on the UDM directly.

[rcrivelli]

yes.
but when i change the order of the DNS servers in the DHCP configuration, it works. In this case the remote DNS has to be the first DNS server. Otherwise UDM-PRO lookup the hostname with 127.0.0.1.

Makes sense it would be that way.  May need to adjust the wrapper script to switch up the DNS.
