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!

Site to Site VPN with access to remote DMZs (Cisco PIX515)

Asked by Rhubarb in Virtual Private Networking (VPN)

Tags: dmz, vpn, cisco

Hi all,

I have a site to site VPN, with site A being 172.16.1.x and site B being 172.16.2.x. This is between a pair of Cisco 515Es with 4 port DMZ cards in each.

Site B also has DMZs 192.168.1.x, 192.168.2.x, 192.168.3.x and 192.168.4.x.

The site to site VPN works as expected, but I would like users in site A to be able to reach services in site B's DMZs, I'm just using a host in 192.168.1.x for testing.

I've added the following to site A's nonat and VPN ACLs:

access-list nonat permit ip 172.16.1.0 255.255.255.0 192.168.1.0 255.255.255.0
access-list 101 permit ip 172.16.1.0 255.255.255.0 192.168.1.0 255.255.255.0

I see the hit counts for these rules increment as I attempt to access the test service.

At site B I've then added access for site A's hosts to reach the DMZ hosts

access-list insidein permit ip 172.16.1.0 255.255.255.0 192.168.1.0 255.255.255.0 eq https

But never see this hit counter increment when I request an HTTPS page from a host in DMZ1.

What rule have I missed?

Many thanks.
