VPN on a ADSL Connection

[Jared Roberts]

I have a Windows 2000 Server Running RRAS Server using PPTP as the Method,
DNS, DHCP, and WINS. The machine currently has a single NIC card. I have an
ADSL connection with a crappy router, Actiontec r4500U. It's made for home
broadband connections. It does allow me to map ports and by default allows
for PPTP passthrough.

VPN Server Config:
IP ADDRESS: 10.0.16.11
Subnet: 255.255.255.0
Gateway: 10.0.16.1

Router Config:
Port 1723 --> 10.0.16.11
PPTP Passthrough is ON
For kicks i allow UDP and TCP Port 47 --> 10.0.16.11 (I understand this
isn't nessecary. I think the pptp pass through does gre port 47)
LAN Address: 10.0.16.1
WAN Address: 262.23.XXX.12
WAN Gateway: 262.23.XXX.1
NAT is Running on this router.
DHCP is OFF

Locally on the LAN i can VPN into the VPN server. I get an address in the
dhcp pool i defined and a PPTP adapter is marked active for that address.
Once I disconnect and use a dial up connection to get on the internet and
then try to VPN into my server I get to Verifying Username and
Pasword....(hangs for 20-30 seconds) then ERROR 721.The remote computer did
not respond. I have even gone to the extreme of sticking the Server in the
DMZ. I did it to just try and get some sort of connection. I don't
understand what's going on. Do I need to put a second nic card in the
Server? If so, how do I configure the Sever's Two NIC cards? Are they on
seperate subnets? Do I configure the server as a NAT server and allow the
server to perform all internet traffic routing? Any documentation or
experience on the matter would be apprecaited.

Thanks In Advanced...
Jared

If you try to contact 10.0.16.11 as a VPN server from the Public Internet,
you will not succeed as that is a non-routable address.

If you could get a public IP on that server you would probably be able to
get this to work. Or, if your router can answer (serve) pptp then you are
set since it's external interface has a public IP.
