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.

Thank you!

Hi Guys,

I have 2x Cisco 857 ADSL Routers. I have 2x sites with ADSL lines installed. Both lines are on dynamic IP addressing. These routers support DYNDNS which are working just fine. They are updating the new IP address's on the DYNDNS website like normal. What I am trying to do it setup a 2 way communication between these two sites. I can do this two ways from what I can see.
1.) Setup one router as a VPN Server & the other as the VPN Client
2.) Setup a site to site connection between both routers

NOTE: the steps above will have to be connected using hostnames and not IP's due to dymanic IP addressing.

Has anyone done this? Please could someone help me?
