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.

Cisco 1841 ISP failover using HWIC-1ADSL and WIC-1SHDSL-V3

Asked by anas_elkhani in Network Routers

currently I have an SDSL and an ADSL on 2 netgear routers from two different providers.  We use the ADSL as a backup when the SDSL goes down.  The problem is that we have to manually move the connection and also change all the IP's and firewal rules when this happens and then put it all back when the SDSL comes back online.

I'm thinking of getting a Cico 1841 with WIC-1SHDSL-V3 & HWIC-1ADSL modules to manage the failover.

the SDSL provider has advised that they can also provide an ADSL connection coming from a different gateway which means that the IP's will always stay the same as they are assigned on authentication whether using SDSL or ADSL.

my question is, if i stick with having two different providers rather than go with the same provider can the 1841 handle the ip changes?  there is a sonicwall firewall after the router that handles all the rules and VPN's.
