Start gns3 vmware esxi9/2/2023 ![]() ![]() It appears that you have changed the behavior of the GNS3 VM. This is how it works in engineering.I can very, very, carefully add new behavior to the GNS3 VM all day long.īut I not permitted to change the behavior of the GNS3 VM. I see no bridge configurations in the GNS3 VM CLI. ![]() You have not shown how you changed the configuration.You appear to have changed the default configuration of the GNS3 VM by manually logging into the GNS3 VM and doing something like "I have my GNS3 VM set up with 2 interfaces, both of which connect to VMNet0 (Bridged Network) via VMware Workstation Pro" - that is not a gns3 developer designed network configuration.Devs are way smarter than I The gns3 developers do not have a "Reset Network Configuration" on the GNS3 VM to return the network configuration as to how they originally designed it. These are just my thoughts, and by no means should be taken as absolute truth. (more can be added, but requires more networking understanding). Eth1, by virtue of it being a bridged interface is in promiscuous mode and is listening to EVERYTHING.ĮSXi, as a Type 1 hypervisor does not have the ability to be on the same host as the desktop client (unless you are doing some black magic deep nested virtualization that you probably should not be doing), thus why it only has an eth0 for the GNS3 VM interfaces. So in your case, you have both interfaces (eth0/eth1) plugged into the same switch. (actually, I believe it defaults to bridging to ALL of the physical interface on the host computer. VMNet0, is also a separate virtual switch, however it bridges to a physical interface on the host system. It basically creates an isolated virtual switch and connects the VM and a virtual interface on the computer to it. This segregates the "control plane" traffic and does not expose it to the real network or the physical devices physical NIC. What is the significance of it being deigned as Host-Only? My configuration for EVE-NG is identical, and I never have this issue.ĮSXi and VMware Workstation are 2 different animals. Seems like there's some weird behavior going on here. it created a huge loop, even when not plugged into a cloud node. This is JUST the effect of creating the connection between the two nodes.ĮDIT: I went ahead and created a bridge (br0) and added eth1 to it to see what would happen. Note: The IOU device isn't even turned on. Even then, it still created a loop (tons of TCP duplicate errors). Note: in the past, I didn't have eth1 I just connected everything to eth0. However, the moment I connect eth1 into my VM environment, eth0 suddenly starts copying ALL of its network traffic into eth1 (and into my GNS3 topology) and creates a loop. ![]() I would expect that, once I hook up eth1 (via the Cloud node) to my GNS3 network, that would stay the same. Under normal circumstances, eth1 receives no traffic (other than broadcasts on my home network). Why do I have eth1 at all? Because I don't want all of the GNS3 Client GNS3 VM traffic copied into my topology. It does not have an IP addressThis is what I connect the "cloud" node to.
