How To Fix AWS Tunnel Connectivity After Replacement Activity

Select Language:

After replacing the AWS tunnel, our connection to our network started acting up. We noticed that we couldn’t access certain resources, and the connection kept dropping randomly. To fix this, I followed a few simple steps that anyone can do if they run into similar problems.

First, I checked the VPN or tunnel settings to make sure everything matched the new configuration provided by AWS. It’s important that the IP addresses, subnet masks, and routing rules are all correct. Sometimes, a small mistake here can cause big connection issues.

Next, I verified that the security groups and firewall rules on both ends are properly set up to allow the traffic through. If anything has changed during the replacement, updating these rules can help restore connection stability.

Then, I refreshed the network interface and restarted the router or gateway device. This helps the network adapt to the new tunnel settings and flushes any old routes that might be causing conflicts.

Finally, I checked the logs for any errors or warnings that could give clues about what’s going wrong. If I saw specific issues, I addressed them by updating configurations or reaching out to support if needed.

Following these steps, I was able to restore a stable connection. Always remember to double-check all your network settings after making a change like replacing an AWS tunnel. Patience and careful troubleshooting can save you a lot of time and headaches.
