Windows Server network setting for DirectAccess/VPN

[dstoler]

So my info is as follows:

1 server running windows server 2012 r2.
2 ethernet cards
1 dd-wrt router
cable modem with 1 port, no routing capabilities (which my router is connected to)

What I want to do is create a VPN/DirectAccess.
Upon configuring it errors out and says the specified external adapter can not be found on the server.

I have nic1 configured to 192.168.1.100, this is the nic that dhcp, dns is installed to and working just fine. My other nic2 is 1.101 and configured to use nic1 as the dns. Both nic's point to the router as default gateway.

I believe my topology should be nic1 connected directly to cable modem and nic2 connected to the dd-wrt router (possibly in the WAN port?) Is this correct? DA/VPN needs an external nic and I do not know if this is right. I am not even sure how I would set up the static ip of nic2 for this to work. My linksys, flashed to dd-wrt does have some vpn settings in it but that is confusing to me as well. Thanks guys!

DA does not need a direct public connection. You can NAT TCP port 443 and it'll work just fine.

The thing is, it will not fully install for me due to this. I am about to go to class and will try out some things later. Thanks for the response.

I am not really certain what the purpose of having 2 nic's on my current set up even does. I would like for one to be on the internet and the other the nic for the lan.

Good security model to use two separate nic's. Can be accomplished with VLAN's to some degree with the proper router. The 2k12 box could in theory could replace the router but that would be an unwise choice as far as security goes!
