MikroTik

Hi,

I bought a RB450 two weeks ago and i'm already loving it ^^.
I've successfully set up, 2 Wan interfaces with fail over, OpenVpn server + clients, and Qos.
Thanks to the Documentations and Wiki !

But i'm still a noob, and i have one question regarding Dns server on RouteurOs.
I have a static entry in Dns that don't work. Since my english is not very good, here's a screen :
http://img24.imageshack.us/my.php?image=dnserror.jpg
As you can see, Static entry "Server" is working but no "Dedibox".

Some informations :
Wan 1 (primary) : 192.168.2.0/24 -> Mikrotik 192.168.2.1
Wan 2 (backup) : 192.168.1.0/24 -> Mikrotik 192.168.1.66 (Yeah my dns reservation is no good on this screen)
Lan : 192.168.0.0/24 -> Mikrotik 192.168.0.254
OpenVpn : 192.168.88.0/24 -> Mikrotik 192.168.88.1

Remote dns request are allowed.

Dedibox host is a Vpn client, but that should not be a problem.

And the best for the end : From a pc on Lan :
-Ping dedibox : KO
-Nslookup dedibox : OK !!
-Ping 192.168.88.2 : OK

Do you guys have an idea ?
Thanks !

well, it seems like ROS do not use local static DNS entries while resolving names for 'ping' command

I don't have any local Dns server, so why should it work with "Server" and not "Dedibox" ?

I tried to add different domain names to ROS DNS, and it cannot resolve them. I think, 'server' is your Windows machine name, and it's resolved via NetBIOS or something. Try to disconnect your ROS machine from the Server, reboot it and see whether 'Server' name works

Thanks for support !

Even if Ros does not use Dns statics records, Ros Dns server should use it for Dns request form clients on Lan !
What is really weird is that nslookup works, but not ping ! This behavior happens on all my Pc on Lan.
Before seting up Ros, i used to have an Ipcop firewall (linux based firewall) with internal Dns server, which worked like a charm.
Nothing changed but the firewall.

Is Ros Dns server stable ? Does anyone encounter the same behavior ?
I don't want to step up another dns server, since i don't have lots of records (Home use).

Anyway, thanks for help

Can someone help me ?

please make a supout.rif and send it over to mikrotik support
I've been seeing a similar dns problem but haven't been able to get enough info on it yet.

if we both send through info it should help them discover what the prob is

i have no problems with router resolving entry from /ip dns static

the only configuration is set primary and secondary dns, allow-remote-requests=no
add entry, and i can ping it without problems. no other place to resolve the entry but local dns cahce/dns static entry. if you see other results - use latest version available.

I'm happy that your Dns are working ....

By the way, i already use the Lastest stable version of ROS (3.20).


omega-00 -> I'll send my config file to support, hope it will help.

yep, checked: with CLI all is working. but try to use WinBox: after successful ping from CLI WinBox says 'Error in Ping To - ip address expected!'. non-local names work fine
