HI

I have changed my old Server for a Mikrotik Server in my network. I have 3 interfaces eth0, eth1, eth2. Interface eth0 is my WAN interfaces, eth1 and eth2 are Local interface. On eth1 and eth2 is masq and all work fine. I use too dhcp server and dns server. My clients become a IP Address, gatway and DNS(first local second out provider). The Internet wokr very good but for example when client go away from computer for 10min and come back the DNS dosen't work and must or Repair connection or reboot computer and all work again fine. I was tried write the DNS on "hard" on client station but te problem is again. I was trided whit diferend DNS.

Any suggestions?

(Sorry for my ENG)

please try to connect several clients ans see if they all suffer the same.

and try just setting up DNS of your MT box and see if DNS works and if problem persist

I have the same problem!

I just setup a RouterOS Box V2.9.40 and everything works fine, but the last step I did was to use the box as DNS which gets me the same problem...

I have my own DNS server insde running and if i point my xp boxes to that machine everything works fine...If i point them to my routeros box they work for some time and then its stops..

I can see the cache getting filled when it works, but when it stops the new requestes don't get added to the cache ?

When the DNS stops working i switch the clients back to my internal server and they work again!

any ideas ?

[janisk@Sumo] ip dns> export 
# mar/22/2007 09:59:55 by RouterOS 2.9.40
# software id =
#
/ ip dns 
set primary-dns=1.1.1.1 secondary-dns=1.1.1.2 \
    allow-remote-requests=yes cache-size=2048KiB cache-max-ttl=1w

this is my dns configuration on a router - pretty default. i have no problems what so ever. and my clients have only 1 dns entry that is my default gw, that is this router.
