Hi, I understand — this is a CLI-only, no-guesswork networking job, and it needs to be done right the first time. I have hands-on experience with Proxmox networking, routing, bridges, VLANs, and multi-NIC cluster setups (Hetzner + internal switches + 10G links). I’m comfortable working fully via SSH and troubleshooting at the routing/table/interface level, not clicking around. I can: Properly configure bridges, routing, and fail-safe networking Separate public (ISP/Hetzner) and private traffic cleanly Optimize your cluster communication over 10G Ensure stable connectivity across all nodes If everything is straightforward, this is a few-hour job, not days. No trial-and-error — I’ll go in with a clear plan and execute. Ready when you are.

As an expert Linux developer with a specialization in networking, I am confident that I possess the in-depth knowledge and skills that your project demands. I understand your frustration with professionals who promise expertise, but end up clicking around without much understanding. Rest assured, my experience of over 8 years ensures that I can effectively work on the complex task at hand. In terms of my technical skills, I have successfully worked with Proxmox on numerous occasions. Networking configuration, routing and setting up network interfaces are tasks I am very familiar with and can handle with ease. Also, as a DevOps expert proficient in CI/CD using tools like Docker and Git, I can ensure efficient deployment and version control without any issues. Moreover, adaptability is one of my strongest attributes. Despite the limitations caused by your environment (no GUI available and only working on the notebook), my extensive skill set encompasses using Linux command line effectively which means I can seamlessly handle this project for you.

Good to see this project, I will configure your Proxmox cluster networking via CLI — bridge interfaces, VLAN tagging, bonding on the 10 Gb NICs, and proper routing between the Hetzner single server and your 4-node cluster over the 1 Gb switch. For the dual 10 Gb NICs on each cluster node, I will set up an LACP bond (bond0) for corosync and storage traffic, keeping that high-bandwidth path separate from your ISP-facing NIC. This avoids cluster heartbeat interruptions when public traffic spikes and gives you failover on the 10 Gb link. Questions: 1) Are the 10 Gb NICs on a dedicated switch, or are they direct-connected between nodes? 2) Do you need inter-node routing through the Hetzner server for outbound NAT, or does each node have its own public IP? Looking forward to discussing further. Best regards, Kamran

Hi, I understand that the main technical challenge here is configuring a Proxmox cluster with complex networking requirements, particularly with two NICs on a single server and multiple NICs across a four-node cluster. This configuration is crucial for ensuring optimal network performance and reliability. Given the absence of a GUI, it's essential to leverage command-line tools effectively to avoid misconfigurations that could lead to downtime or performance issues. Your need for a true expert resonates with my extensive experience in configuring network interfaces and routing for virtualized environments. I have worked on similar projects where I optimized network traffic and ensured seamless communication between nodes, focusing on minimizing latency and maximizing throughput. In my previous roles, I dealt with complex networking setups involving multiple interfaces and clusters, successfully implementing solutions that improved network stability and performance. My hands-on experience with command-line configurations and troubleshooting in Proxmox will allow me to address your requirements efficiently. My approach would involve: - Assessing the current network setup - Configuring NICs and routing protocols directly via the command line - Testing connectivity and performance across the cluster - Documenting the configuration for future reference. What specific performance indicators do you have in mind for this setup? - Are there any particular routing protocols you would like to use? - What is your expected timeline for having this configuration implemented? Sincerely, Shaun

Hello! I understand you need a Proxmox networking expert who can configure your server and cluster's multiple NICs without GUI access. I'll work directly via your notebook, focusing on your setup: a single server with dual NICs and a 4-node cluster with varied NICs for ISP, switch, and 10 Gb connections. My approach is to first assess current network routing and interface configs, then optimize routes and bridges, ensuring smooth communication across your cluster and internet. I'll handle this efficiently and directly without wasting your time clicking around. I’m confident I can get it done right and fast. Can you share the current network and routing configuration files so I can understand the baseline setup before starting? Are there specific requirements or preferences for how the 10 Gb NICs should be used in the cluster? Is there any special network traffic segregation or VLAN setup you need across the NICs? Do you have any existing firewall or security rules configured on these systems? Would you like me to document the configuration steps I implement for your future reference? Looking forward to helping you get this network solid! Thanks,

Hello, I completed a similar project two months ago and am confident I can lead this one to success. With 4+ years of experience in Linux, I specialize in network configurations and routing. I understand your requirement for Proxmox cluster networking setup without GUI, ensuring a seamless connection between servers and switches. Let's discuss further in the chat to provide a professional solution tailored to your needs. Best regards

I am an experienced infrastructure engineer with network and linux system administration background. I've worked with proxmox VE since 2014. I can help you with your networking - if you have access to the switches/networks and servers via terminals. It would be helpful if you explained exactly what you want to accomplish with the interfaces, I understand that you have one for internet access, one to the switch, and then the 4 node cluster is connected to the same switch. Do you want all the internet traffic to pass through the first server and then have inter-node communication on a private network?

I have strong hands-on experience with Proxmox VE networking and Linux-based network architecture, including multi-NIC servers, bridging, routing, and cluster networking without GUI (CLI-only environments). I understand your setup clearly: Single server with 2 NICs (Hetzner uplink + 1Gb switch) 4-node Proxmox cluster with: NIC0 connected to ISP NIC1 connected to 1Gb switch (likely management/cluster network) Dual 10Gb NICs for high-speed traffic (storage / migration / VM traffic) I specialize in designing and fixing complex Proxmox network topologies including: Linux bridges (vmbr) design and separation of traffic domains Static routing and correct gateway handling in multi-NIC environments Bonding/LACP configuration for 10Gb links Proper isolation of cluster (corosync), management, and storage networks Avoiding asymmetric routing and network lockouts during CLI-only configuration I work strictly via SSH/terminal and focus on precise, production-safe changes with step-by-step validation to avoid downtime. I can complete a correct and stable configuration within the expected short timeframe once access and current config are reviewed.

@yousefmohamedme9

I understand you need precise, command-line–level Proxmox networking configuration with no trial-and-error. I work directly with Linux networking (iproute2, bridges, VLANs, bonding, routing tables) and Proxmox cluster setups, and I’m comfortable operating entirely over SSH without any GUI. Based on your setup (single server with dual NICs and a 4-node cluster with mixed 1G/10G links), I will design and implement a clean, deterministic network layout: WAN isolation on ISP NICs, dedicated cluster/Corosync network, optimized storage/replication over 10G, and proper bridge configuration for VMs. I’ll handle routing, static routes, possible VLAN segmentation, and ensure no asymmetric routing or MTU issues. If needed, I can configure bonding (LACP or active-backup), verify link states, and tune for performance and failover. I don’t “click around” — everything is scripted and validated step by step (interfaces, routes, ARP, connectivity tests, failover checks). I can complete this efficiently within a few hours, provided access and requirements are clear. We’ll review your current config, fix what’s broken, and leave you with a stable, documented setup you can maintain.
