Please help it's emergency

[kla]

I need some help if it's posible.

I have to configure 2 network cards on a computer that should serve as a DNS server on a OpenBSD as an OS.

As much as I understand network cards are configured in hostname (network card name).

When I opend that file (concrete hostname.d0) was written:

dhcp NONE NONE NONE

And following the instructiones for openBSD I wrote

inet IPadresa-računala 255.255.255.0 NONE

Is that ok?

Also, I can't find how to configure second network card. I know that one should be configured for local network (for about 10 computers) and another for "going out" (-apology for bad english i'm from croatia) but i don't understand how to configure which one more specific in which one do I write for example IP of gateway.

I made in /etc mygate directory in which I wrote gateways IP.
As I could understand from manual gateway should be read from there by default.

For now when ever i ping some other computer or server I get the message

"no route to host".

Can somebody please help?

again sorry for bad english I hope you understand what is my problem and that you can help me
