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!

Cannot ping over IPSEC VPN between ZyXel ZyWall 5 and pfsense

Asked by jdroger2 in Virtual Private Networking (VPN), Network Routers, IPSec Security Protocol

Tags: ipsec vpn zyxel zywall pfsense

I am replacing one end of a site to site IPSEC VPN.  Both ends used to be pfsense but now on one end I am using a ZyXel ZyWall 5.  I believe I have the two endpoints negotiating both phases properly, and the VPN shows up as active and working in both the pfsense and ZyWall interfaces.  I just cannot ping either network from the other side.  the main office network (with the pfsense) subnet is 10.10.10.0 /24 and the satellite office network (ZyWall) is 192.168.10.0 /24.

as far as firewall rules go, on the pfsense I have an IPSEC rule that traffic is wide open (works on all other VPN endpoints) and on the ZyWall i have the default setup, which is OPEN.

Here is a line from the ZyWall logs which I think describes a computer at the main office trying to ping the ZyWall:

# Time         Message                                                           Source          Destination          Note
3  [xx]       ip spoofing - WAN ICMP (V to V/ZW, Echo)        10.10.10.25       192.168.10.1       ATTACK

thanks!
