#WIRESHARK LINUX VIRTUAL MACHINE MAC#

Ensure that all VLANs required for communication are configured correctly.

Verify that the physical switches to which your ESXi hosts are connected allow Promiscuous Mode and don't have any restrictions that could prevent traffic visibility between hosts.ĭouble-check the networking configuration on each ESXi host, including VLAN configurations and uplink connections to the physical switches.

Check that the Distributed Port Groups for both WAN and LAN have the same configuration (Promiscuous Mode, MAC Address Changes, Forged Transmits) set to Accept on all hosts. Let's explore some potential causes and troubleshooting steps.Įnsure that the vDS settings are consistent across all hosts in the cluster. The issue you are facing with Kali Linux VMs not being able to capture traffic on Wireshark when VMs are on different hosts than the PFSense could be due to several factors. It seems like you have set up a complex networking environment with PFSense, vCenter, ESXi hosts, and multiple VMs on different Distributed Port Groups (DPGs) and VLANs. You can change promiscuous mode on a standard vSwitch on a host, not a Distributed vSwitch in vCenter. You can only change promiscuous mode on the Distributed Port Group. It's just a Wireshark issue not being able to capture the traffic.Īlso, these VM's are on a Distributed vSwitch and Distributed Port Group in vCenter. Now, mind you, all these VM's are connected to the PFSense and are getting a DHCP address from it and they are able to ping each other. If you do a packet capture from a VM on another host that the PFSense is not on it will not capture anything at all. The host that the PFSense resides on if you do a packet capture on a VM on that same host it will pick up traffic from any other VM getting a DHCP address from the PFSense on any other host. If it is not fully working as expected did you enable promiscuos mode on the actual virtual switch (not just the port groups)? promiscuos mode on the vswitch will effectively turn it into a hub so traffic is sent to every port - then by defualt every port group on the vswitch will recieve the traffic (if not manually overridden). If it is not fully working as expected did you enable promiscuos mode on the actual virtual switch (not just the port groups)? promiscuos mode on the vswitch will effectively turn it into a hub so traffic is sent to every port - then by defualt every port group on the vswitch will recieve the traffic (if not manually wrote: In your first post I understood that the VMs could not see the traffic if on another host.Īny VM on that new host can capture all the traffic from all other VM's in that subnet regardless of the host' then it is doing what you need right? Port Mirroring should have nothing to do with that. Any VM on that new host can capture all the traffic from all other VM's in that subnet regardless of the host. I can vMotion the PFSense VM to another host and it's the same thing. I'm still wondering why any VM (with a DHCP address from the PFSense) that's on the same host as the PFSense can capture traffic from all other VM's on that subnet regardless of what host the other VM's are on. I'm trying to capture traffic between all VM's that have a DHCP address from the PFSense. you could source the vlan or juts the pfsense port-group, the desitnaiotn will be a new distributed port for your VMs. Using 3 VMs is an added challenge - you might need 3 port mirrors. You do not mention a port mirror - a port mirror is required to soruce the traffic and copy it to the destination (in your case the 3 VMs). You actually state your objective - is it to packet capture all traffic from the LAN to the pfsense? or WAN to pfsense? both?
