DHCP Issues with VPN Connections on Server 2012 R2


(trying r2 setup forum, since i'm using r2 instead of vanilla 2012)  reinstalled windows server 2012 r2 today , struggling vpn access using dhcp.  if define static block of addresses, works - not correct configuration.  how can configure server 2012 allow connecting clients addresses network router's dhcp service?

setup process:

  1. install windows server 2012
  2. install remote access role "direct access , vpn (ras)" feature only
  3. run "getting started" wizard , deploy vpn only
  4. "configure , enable routing , remote access"
    custom configuration
      vpn access checked
  5. configure nps

after this, can only connect static ip block defined.  testing local computer, lan computer , remote computer; using pptp , l2tp/ipsec.  connections work fine static block.

i randomly able connect , dhcp addresses router once earlier today, , thought had set correctly finally.  rebooted server make sure durable, , no longer connect without static block.

the router standard consumer 192.168.1.x gigabit router.  has options manners of vpn passthrough; when attempting connection 127.0.0.1, behaves same way connection goes through router (won't connect dhcp ip address, connect static block ip address).

while connection being attempted, there brief period of time, 3 seconds, if refresh "remote access clients" list in rras see user attempting connect.  there no network address listed, user there until dhcp request fails , connection terminated.

ras event log message:

routingdomainid- {00000000-0000-0000-0000-000000000000}: coid={na}: user {unimportant} connected port vpn0-127 has been disconnected because no network protocols negotiated.

hi,

have configured dhcp relay agent correctly?

since clients , server in different broadcast domains, dhcp relay agent necessary clients ip addresses.

you can refer following articles:
