If you'd like a better explanation google DNE Lightweight Filter and do some research. The chances of loopback and localhost tests failing are very low compared to other network configuration problems. I do not understand the feature and cannot explain why it works. I'd do a packet capture on the loopback interface using wireshark and there was nothing!įIX: Go to loopback properties and remove the check beside the line that reads "DNE Lightweght Filter" For some reason this setting, when checked, filters traffic coming in from GNS3. My issue was that NO TRAFFIC was being passed between the router and the cloud.
UNABLE TO PING LOOPBACK ADDRESS DRIVERS
This problem may occur if any one or more of the following conditions is true: The TCP drivers are corrupted. On Red Hat based distros like CentOS, and Arch Linux based distros like Manjaro, use the -6 option with ping command to force IPv6. You can actually run GNS3 with the firewall on as long as the proper rules are in place. Answer JR John Rubdy Replied on AugReport abuse Hi, Were there any changes made on the computer prior to the issue If the loopback test fails, the IP stack is not responding. On Debian based Linux distros, including Ubuntu, you can use the ping6 command to force ping to use IPv6 instead of IPv4.
Nor was I facing a permissions issue or a firewall issue.
flags73R1 - īoth devices have IPs configured for same subnet. I am unable to access my home network from WSL2 subsystem. Every time I reinstall GNS3 whether it be standalone or all-in-one I run into a problem when my router cannot ping the MS loopback adapter.
