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! |

Asked by RobWasho in Network Routers, Networking Hardware Firewalls, Virtual Private Networking (VPN)
I have 1 main site (London) where the DC and Exchange server is and 1 satellite site (Colchester).
In each site the local network goes through a Sonicwall TZ 170 Standard Firewall which goes through a Draytek 2600 Plus. A VPN connection is configured at the London Site to connect to Colchester.
A Firmware upgrade was performed on the Draytek router at Colchester. SInce then Colchester cannot connect to the London site for authentication or email. They do have Internet access though.
Both Sonicwall devices are advising various messages in the log: IKE IKE negotiation aborted due to timeout, THEN > IKE Responder: Received Main Mode request (Phase 1) (from London) THEN> IKE Responder: No response - remote party timeout THEN > Received packet retransmission. Drop duplicate packet (London)
Is there anything in thr Draytek which would block access to the VPN ie passtrhough as this is the only thing that has been changed?
