Setup DNS Mikrotik
ALTERNATIVE PROCEDURE IF YOU WANT TO INPUT A FIXED IP/GATEWAY/DNS
(instead of using DHCP on the ether1 port)
Use care in selecting the DNS SERVER IP address in the setup below. You
MUST select an actual DNS server or a router which provides DNS services.
Some routers (such as the Hawking FR24) provide a "DNS RELAY" feature on
the gateway address which redirects DNS service requests that are sent to the
router Gateway Address to some downstream DNS Server. Such "dns relay"
service is not always compatible with the Mikrotik system. Other routers (such
as the NexLand 800 Turbo and many other router setups) do provide normal
DNS Services on the gateway address. In many routers it may depend on user
The Mikrotik router will NOT resolve DNS properly for the Hotspot unless the
pointer to a DNS server source points to a "real" DNS Server or a router which
actually provides DNS SERVICES on the Gateway address. The result of no
DNS service will be that your hotspot lin screen will not be loaded when "any
URL" is transmitted to the ether2 (Hotspot) port via your browser. This problem
can be very confusing to diagnose.
You can test what DNS address you should setup in the Mikrotik unit by
running an ip configuration test on a Windows equipped computer connected to
your router that you also intend your Mikrotik to use for internet access.
Proceed as follows:
b) In your windows computer, in network settings, select tcp/ip properties, and
select "obtain an IP address automatically" and "obtain DNS server address
automatically". Click OK and exit and reboot if necessary to activate the new
settings. Then execute Setup>Run>
then enter <winipcfg>, click OK, (windows 95/98), or <ipconfig>, (or perhaps
wntipcfg), click OK, (windows XP/NT/2000), In Windows , you may have to
download the winipcfg.exe (or similar) module from the resources folder on the
install disk to get this to work. You will get a display such as the image below
