The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

VPN W2K IP mess

Asked by ITGL72 in Windows Networking

Tags: vpn, w2k

I have a windows 2000 server on a 192.168.1.0 internal network. It’s the VPN server.

I noticed my problem when first connecting to the server. Its behind a DSL connection using a linksys router. Port forwarding is setup for VNC and VPN connection. I can connect via VNC and connect via VPN.

But on the VPN connection, I cannot PING other machines, or map drives. I cannnot even VNC to the same machine I am able to VNC to when I just hit the outside IP.

Heres what I have configured on the Routing and Remote Access MMC. I have it setup to issue from a static pool of IP addresses 192.168.1.222 through 192.168.1.227, HOWEVER FOR SOME REASON --> its not giving me a SUBNET MASK of 255.255.255.0! I cannot change it.        

THIS IS THE W2K SERVER IP STATIC CONFIGURATION:

DHCP Enabled. . . . . . . . . . . : No
IP Address. . . . . . . . . . . . : 192.168.1.200
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1
DNS Servers . . . . . . . . . . . : 166.102.165.13
                                    166.102.165.11



THIS IS WHAT THE VPN CLIENT CONFIGURATION LAST TIME I CONNECTED:
Description . . . . . . . . . . . : WAN (PPP/SLIP) In
Physical Address. . . . . . . . . : 00-53-45-00-00-00
Dhcp Enabled. . . . . . . . . . . : No
IP Address. . . . . . . . . . . . : 192.168.1.223
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Default Gateway . . . . . . . . . : 192.168.1.223
DNS Servers . . . . . . . . . . . : 166.102.165.13
                                    166.102.165.11


Two things stand out for me when looking at the information. The SUBNET MASK it is giving the client is 255.255.255.255. But inside Routing and Remote Access were I look at the static pool of addresses, for 192.168.1.222 through 192.168.1.227 it issues a SUBNET MASK of 255.255.255.192 where I would expect 255.255.255.0.

Also, is the VPN clients Default Gateway supposed to be the same as the IP address it received?


ALSO, if I am connected on a network say at home that uses 192.168.1.0/24 and I connect to a remote network that is also using that 192.168.1.0/24 type network would this sort of conflict I am experiencing now occur?

I'm open to options... Thanks...
