Unable to Establish Connection Between Host and Container via GNS3 Cloud Node #2386

Open nazdridoy opened 2 weeks ago

Description

I am experiencing an issue with GNS3 on my Arch Linux machine (no VM). I am trying to connect my container in GNS3 to the internet through my physical Ethernet interface "enp0s20f0u1c2". I have added "enp0s20f0u1c2" in the cloud node and connected my Ubuntu container to this cloud node.

The container successfully receives an IP address from my home router's DHCP, and it can connect to the internet. All hosts on the same network (192.168.0.0/24) can reach the container, and the container can ping all of them. However, there is an issue with connectivity between the host running the GNS3 instance and the container:

Steps to Reproduce

  1. Run GNS3 on Arch Linux (no VM).
  2. Add the physical Ethernet interface "enpXXXX" to the GNS3 cloud node.
  3. Connect an Ubuntu container to the cloud node("enpXXXX").
  4. Obtain an IP address for the container from the home router's DHCP.
  5. Try to ping the container from the host and the host from the container.

Troubleshooting Steps Taken

Is this behavior intended, or is it a bug? How can I establish a connection between the host and the container connected via the cloud node?

Thank you for your assistance.
