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 IPSec not working with Linksys WRV54G, but worked with BEFSR41

Asked by notnevel in Virtual Private Networking (VPN)

Tags: , , ,

I've been using a Linksys BEFSR41 router to connect multiple computers to my cablemodem.  One computer connects to my office network through a NetScreen VPN (Computer->NetScreen->Linksys->...).  This has been working fine.  However, my wife needs to connect her work laptop to her office network through a software (SonicWall) VPN.  

With my Linksys BEFSR41 router, EITHER my computer or her computer can connect to our respective office networks, but if both of us try at the same time, we both suffer very bad packet loss (making the network effectively unusable).  I also tried the Linksys BEFW11S4V4, and got the same result.

I saw an answer to a related question here:
  http://www.experts-exchange.com/Networking/Q_21117201.html
and from the Linksys knowledge base here:
  http://linksys.custhelp.com/cgi-bin/linksys.cfg/php/enduser/std_adp.php?p_faqid=596
that the BEFSR41 and BEFW11S4V4 can only handle one IPSec passthrough at once.

So, I bought the WRV54G and replaced the BEFSR41.  Everything non-VPN related is working fine.  I tried to connect one of the VPN computers at a time, but NEITHER of them worked (even separately).  I confirmed that the IPSec was enabled on the WRV54G setup.  I just can't get any VPN connection working.  

I realize that the WRV54G has lots of advanced features to actually do the VPN authentication/tunnelling.  I don't need this or want this (I don't think), since the one computer has the Netscreen hardware box, and the other computer has the SonicWall software, both already configured by our companies.  

First, I just wanted the WRV54G to do the VPN IPSec passthrough like the other router did (which I didn't think would be a problem), and second, I want to have both of them working at once.

Is it possible for the WRV54G to allow two IGSec passthrough connections at once?  Is there some type of configuration of the WRV54G that I'm missing?  Besides making sure IPsec passthrough was on, I didn't see any other relevant parameters.

By the way, on all the Linksys routers, I upgraded to the most recent firmware versions before doing any of this.  

Any suggestions?
