Trouble configuring local network on 2012 R2

I have trouble configuring local network with NAT. I come from 2003 servers, where that was a breeze. On 2012 something seems not quite right.

I have 2012 R2 server with following services (main):
AD DC
RRAS
DNS
DHCP
(NAP is also there, but I don/t think I will use it)

AD DC works OK, as it seems
DNS should, configuration is simple enough, and all IPs is selected
DHCP doesn't give out addresses, regardless it is activated and set up
RRAS is configured thru Wizard, with two NIC intrfaces, internet and local, and Firewall is turned off for testing purposes

What happens is that I connect other computer to switch on server local NIC, and it doesnt't give out addresses, or anything else. - Is there a checklist I should do, and is there some service that blocks internet access by default?

YES! Immediately, and nothing.

I did this loads of times on 2003, but it just doesn't work whatever I do.

OK then.  

1. you should not be multi-homing a Domain Controller.  Having 2 NICs active on the DC will cause problems and it is not recommended by Microsoft.
2. is this server on the Internet without a firewall protecting it?
3. when you go into DHCP Manager and click Manage Authorized servers, what IP is the DHCP running on?  Is this your local network or the Internet network?

What I would do to troubleshoot the setup:

1. disable RRAS
2. Disable Internet NIC interface
3. from local network, ping server, do an NSLOOKUP of the server's IP and then hostname, verify DHCP address is given out.

NOTE: With the introduction of Windows Server 2008 RRAS would no longer provide firewall and proxy services as found in 2003.

You are not able to run this kind of setup as we used to do back in the day.

Here are the options shown in the RRAS Wizard:

Note the lack of Firewall/Proxy as an option.
