No interetn when using static IP on a Windows domain

Hi Guys,

Would really appreciate some help with this one.

I have setup a new domain controller, running Server 2012. Configured DNS, DHCP, AD DS (correctly to the best of my knowledge- So maybe not!).

My local workstations have been connected to the domain and I have also connected 2 other Win Server 2012 servers.

When the devices (any and all) have IP addresses assigned by the DHCP server, they have lan and wan access. However, if I assign static IP addresses (out of the scope of the DHCP) they still have access to the lan but they cannot Access the wan. Again if I change it back to DHCP assigned IP the device will work fine.

I'm guessing I've missed something in the setup/config of the DHCP server but just not sure what that is. Any suggestions greatly appreciated.

Thanks for your help.

Nick.

Your default gateway must be 192.168.1.254, why are you using 192.168.1.5?

Plus, have you configured your DNS to use 61.9.194.49 as forwarder? http://social.technet.microsoft.com/Forums/windowsserver/en-US/720645c4-0d49-49bf-a76d-70d76e9df9ce/how-to-configure-dns-forwarders-in-windows-2008-dns?forum=winserverNIS

I think your static IP is not on same network segment that default gateway or missing some value on TCP/IP config, Could you explain your DHCP scope and what static IP config have got?

Yeah Sure thing:

DHCP Scope: 192.168.1.100 - 192.168.1.200

DHCP Server (also DC):
IP: 192.168.1.5
Subnet: 255.255.255.0
Default GW: 192.168.1.254 - Router Address
DNS: 61.9.194.49

Hyper V Server 1-Worked fine before adding to domain, works with DHCP assigned ip:
IP: 192.168.1.6
Subnet: 255.255.255.0
Default Gateway: 192.168.1.5 (DHCP/DC Server)
Preferred DNS: 192.168.1.5
Alternate GW: 61.9.194.49

Hyper V Server 2-Worked fine before adding to domain, works with DHCP assigned ip:
IP: 192.168.1.7
Subnet: 255.255.255.0
Default Gateway: 192.168.1.5 (DHCP/DC Server)
Preferred DNS: 192.168.1.5
Alternate GW: 61.9.194.49

For the other workstations I've had various IP addresses etc. When DHCP is assigned on any device, servers included, the only thing that I can see that changes is the IP, obviously because the DHCP changes it to fit in the scope. Everything else appears to stay the same.

Is there a possibility I've missed something when setting up DHCP? Is there an area to add approved static IP addresses?

Thanks heaps.

Nick.
