DNS resolution for OpenVPN cleints
-
Hello all
Trying to clarify some settings related to my DNS server and OpenVPN clients
I see in information my DNS as:
DNS server(s)
127.0.0.1
8.8.4.4
156.154.71.1
129.250.35.251My OpenVPN client log shows:
2017-06-18 09:41:24 OPTIONS:
0 [route] [192.168.90.1] [255.255.255.0]
1 [redirect-gateway] [def1]
2 [route-gateway] [192.168.2.1]
3 [topology] [subnet]
4 [ping] [10]
5 [ping-restart] [60]
6 [ifconfig] [192.168.2.3] [255.255.255.0]I'd like OpenVPN clients be able to resolve hosts by name, but not sure how to make it happen
Thx in advance!

In the OpenVPN setting enable 'DNS Server enable'.
Verify DNS1 is your own local server.
-
i tried that so far with no luck :(
my Subnet 192.168.90.0
i enabled in VPN-OpenVPN-Servers - "DNS Server enable" "Provide a DNS server list to clients" and added "DNS Server 1" 192.168.90.1
looks ok?
-
I have this enabled too: Redirect Gateway - Force all client generated traffic through the tunnel.
See if that changes it for you.Plus this setting, Force DNS cache update.
-
i had "Redirect Gateway Force all client generated traffic through the tunnel." enabled
and enabled "Force DNS cache update" and no love still -
Are you accessing the hostname with the FQDN like printer.mydomain.com ?

i do now!!!!
seems working, thx a million !

Great ! :)

Had to dig out this old post, but it's exactly the same issue, so hope can be resolved ...
I made a copy of my existing OpenVPN server and added a second one.
All same settings. But no matter what I do I can't get host names DNS resolutions on the second server !Wonder WTH and how to troubleshoot it ?
-
Either I missing something or it's a bug in VPN sever setup
What else has to be set in order to pass host names to a VPN client?
Looking for experts...
-
It's always worked for me with just the domain and the DNS servers specified. (No force cache update checked). What does ipconfig /all show on the TAP adapter client side?

I’m on iPhone OpenVPN client
Shows my tun ip -

Sorry, I've got nothing for that. I've only had to deal with the name resolution on Windows and Android devices.
Edit- the OpenVPN connect client (at least on Android) shows the domain and dns pulled in the connect log. -
I think it would not matter what client.
In my case this is how I test. Connect to cellular network on iPhone, connect to VPN and ping host by name. And my 1st server works as expected, but the new server does not !!!

This would seem to indicate a problem with the new server on the DNS server. If you're testing from the phone, maybe get an app that does nslookup or dig.

Well after lots of testing and trying here is why.
I had DNS Resolver options checked for:
'Enable Forwarding Mode'
'Use SSL/TLS for outgoing DNS Queries to Forwarding Servers'Un-checking them and checking back fixed the problem!
I suspect that reboot will help as well, but I not very often reboot my router.
Hope maybe beneficial to somebody else.
