How to get NAT working on 2012 with dual nic?

I have two NIC card on AD 2012 R2 server. I have configured DHCP, which gives addresses correctly.

On one NIC I have internet connection, on other I have LAN.

I tried configuring NAT in RRAS, which is quite straight forward, but the connection doesn't work for the server, or the clients. If I turn off the RRAS NAT, all is fine on the server.

How should I configure NIC cards and RRAS NAT to make this work? I am pulling my hair here.

Usually what happens is if you switch the incoming and outgoing traffic (the LAN becomes the "internet" side, and vice versa). Are you sure you assigned the correct side to each NIC?

I just rechecked it, and it is correctly wired.

Also, I get this error when enable nat.

Do you even use NPS? If not, it maybe smart to remove this Role from this server.

Will remove, but I found out the culprit. - The DNS forwarders didn't work. ISP's server was down.

I literally started pulling my hair out.

Hell, what a stupid situation.
