Hi everyone, I just added a fourth node to the cluster (3 active nodes). I bought a dual Intel 82546 LAN Gigabit Dual Chip 8492MT card and after configuring everything as in the other nodes, the dual gigabit ethernet card does not receive or transmit traffic. I tried to create a vm, and it only works between the node and the VM, that is, they can be seen on the network, but in the switch they are isolated from all other hosts. I bought two other network cards not of the same type but single. The fact remains that I would like to try to understand where the cause of the defect lies. I can only say that in the past with different intele cards on different operating systems I have had very similar problems regarding the card link, I mean the physical one. Thanks to anyone who can provide me with feedback.

Are there any configs on the switch like (untagged) VLANs that might be the cause? What if you plug in that NIC to the switch port that is used by another server where it works? This should help to get some idea where to look for the problem.

Does a ping to / from the server directly work?

Can you show the contents of the `/etc/network/interfaces` file? Best enclosed in [code][/code] tags for better readabilty.

Hello and thanks for the reply .
The switch has no vlan (TP-Link TL-SG105 Switch 5 Gigabit Ports, 10/100/1000 Mbps)
The nodes communicate seamlessly with each other, ping other servers and get pinged, make ssh connections and more. I think the problem is on the nic in question that as written in the past I had similar problems related to the link, later solved with the proprietary intel drivers. Also considering that the Intel cards are sensitive to the type of cable used, I made sure of the cat 5e.
However, if I ping from the node to a server nothing is traced by the pfsense, on the contrary if the nodes ping the firewall or vice versa it is visible. As previously written the dual gigabit card I removed it because there was no way to make it work, I am strongly suspicious of the intel drivers to install. attached the photo of the current configuration of the main node.
The mystery reported in this post always remains.

Hi, I changed the nic, with single cards and the network works, so I assume according to my technical skills that the problem is in the management of this dual gigabit card, or I was not able to fully understand the problem. Thanks for your post.
