This is really a bit of a can of worms. New problems may just keep
popping up. AD plus NAT plus PPPoE plus Macs!
If you must use your DC as the Internet router, you certainly should be
using RRAS and NAT (not bridging). For AD to work, all the AD clients should
be using the 10.0.0 IP addresses you used to set up AD, and they should be
using the local (10.0.0.x ) DNS server.
The server has an Internet connection using PPPoE. With W2k3 this can be
set up within RRAS. The PPPoE interface becomes your "public" interface for
NAT. The 10.0.0.x interface of the server becomes the private interface in
NAT. NAT allows the LAN clients to share the server's Internet connection.
The LAN clients get their config from DHCP on your server. They should
get an IP in the 10.0.0.0 subnet and a default gateway and DNS setting of
your server's 10.0.0 address. You will need to modify your local DNS so
that it forwards requests to a public DNS server (such as your ISP's DNS).
When you have AD and NAT working, you can experiment with VPN. Enable
remote access in RRAS and try making a VPN connection from a LAN client.
(VPN will work over the local LAN). This will let you debug the VPN config
on your server locally.
Because your RRAS server is a DC, you may get name resolution problems
when a remote access client connects. See KB 292822 .
When this works, you can try connecting from a remote client. Your
no-ip.com address should point you to the server's current public IP. If it
works internally, it should work over the Internet.
