Hi! first of all, thanks for reading.

I've configured OpenVPN server on my Archer C5, almost everything is working, i have remote clients which can connect BUT dns resolution for other equipments in the LAN (i mean the remote lan, let's call it the office where the Archer is working). I can ping those hosts by ip through vpn, but it's impossible to do it by hostname.. i've tried configuring "dhcp-options dns" in the client with the default gw/dns for the office (192.168.0.1) also tried with the main vpn internal first ip (10.8.0.1) but couldn't make it work.

Is this normal or am i doing something wrong? 

Which mechanism is using Tplink Archer (and others home routers) to do internal resolve? Local dns cache? Netbios?

Why openvpn clients cannot obtain hostnames from the Archer? 

Thanks in advance!
