Don't worry about the subnet mask. That really only indicates
that you are using a point to point connection. All traffic for
192.168.1.x addresses will go over the VPN connection to the VPN
server. That server will act as a proxy for the remote, and transfer
the data to the LAN. As far as TCP/IP is concerned, your remote
machine is just another local machine. The server proxy operation is
transparent to the LAN machines. As far as DNS goes, if you have the
correct IP addresses for
your LAN DNS server, you should be able to ping LAN machines by
their full name (eg machinename.domain.local). If you can do this
but want to be able to use just machinename , put the domain name
(domain.local in this example) into the connection-specific DNS
suffix on the client machine. Mustafa wrote:
The information for my VPN connection is (slightly altered) as

Description . . . . . . . . . . . : WAN (PPP/SLIP) Interface
Physical Address. . . . . . . . . : 00-53-45-00-00-00

Is the "Subnet Mask" okay? My normal internet connection is
255.255.255.0. What about default gateway?
Thanks again everyone.

To confirm what the DNS address is, do an ipconfig /all on the
client while connected to VPN. It should show the address of the
DNS server at your office for the VPN connection.
You set the DNS suffix in the Advanced TCP/IP properties of the
VPN connection.

Thanks again for the responses, but I don't understand how to
confirm whether the client receieves the correct DNS address when
it connects and/or how to set the correct DNS suffix. Where do I
check the office domain name?
Thanks.

You should be able to access your office machines by their DNS
names. Does the client receive the correct DNS address when it
connects? As well as the correct DNS server address, you need to
use the correct DNS suffix. If your office domain name is
company.com , then you need to put this in the connection
properties of the VPN client. If you don't, you will need to use
the FQDN of the machines (eg
machine.company.com) to resolve thier names to IP addresses.

thanks for the info, one more clarification if you please:
1. i also lose my local internet connection when connected to
the VPN. any ideas?
2. when i'm on my laptop at my apartment (where we also have a
router), my local IP is something like 192.168.1.105 or
whatever. if I'm trying to access a computer on the network
that I'm connecting to via the VPN (say my office pc), and its
IP address at the office is 192.168.1.105, isn't there a
conflict at this point? even if the IP's differ, when I type
//192.168.1.105 or whatever how does the network know which
"192.168.1.***" network I'm referring to? 3. Can anyone please
point me to information regarding WINS/DNS
and how to set it up so I can access my office resources via VPN
by name? As I mentioned, I have zero experience regarding this
subject; I'm just trying to set it up so we can share resources
when on the road. Thanks again, much appreciated.

A VPN link doesn't carry broadcasts, so you cannot resolve
names by broadcast. If you are not using DNS or WINS, you will
need HOSTS or LMHOSTS files on the client to resolve names to
IP addresses. Mustafa wrote:
Hey All!
Thanks for the help. I think I found the error, my router is
set up to assign IP addressed from a pool and the RAS server
wasn't expecting that. I made the change to assign addresses
from the same pool and now I can at least connect to the VPN.
Now, I cannot access resources it seems. When I try to go to:
\\computername
it tells me it is not accessible. Is there some other way I
should refer to the computer?
Thanks again!

ras error 733 is tcp/ip protocol or dhcp issue. do you have
DHCP? quoted from
http://www.howtonetworking.com/raserrors.htm *Error 733*: the PPP
control protocol for this network
protocol is not available on the server.
Resolution:
1) Ensure that the TCP/IP protocol is installed on your RAS
server and that the TCP/IP protocol is selected in the Server
Settings of the Network Configuration option of the Remote
Access Setup dialog. 2) If you have the "Use DHCP to assign
remote TCP/IP client addresses" option selected for the
TCP/IP protocol in the RAS Server Settings, then ensure that
you have installed DHCP and
that it is not disabled. 3) Ensure that all of the bindings
for TCP/IP are enabled in the Bindings tab of the Network
dialog of the Control Panel. Be sure to
inspect the TCP/IP Protocol and WINS Client (TCP/IP) bindings
for all adapters, all protocols, and all services. If the
TCP/IP bindings are corrupt, you may have to reinstall TCP/IP
and or RAS in order to clean up the bindings.

Hello Everyone,
We have a static IP address at our office, this line comes
into a Netgear MR814v2 router which has been configured so
that it forwards the
ports 1723 and 499-501 to our Windows 2003 server. This
server is set up
as our VPN server. It only has one Ethernet card in it which
is connected to our router. Via the RRAS panel, I've created
the policy to allow VPN connections and when I try to connect
to the VPN via another computer running Windows XP sp2 either
by using the server's local ip (192.168.1.184) or our static
external IP, I get the same error, #733. Oh, also, our Server
is not a domain server. It is merely to be used for
things like file serving, web serving, etc.
I'm very new at this as network administration is not my
background; we are a small company and just want to get a VPN
server set up so we can access our local resources when
travelling. Thanks in advance for any and all help.
