    Proxmox HA Cluster Setup
    6 dní left
    Ověřený

    I need an experienced Proxmox engineer to stand up a 3-to-4-node cluster and tune it for true high availability and fast replication. All hosts will run Proxmox VE on hardware RAID 10 arrays (we are intentionally staying away from ZFS for now). The cluster must serve both Linux and Windows virtual machines and allow live migration without interruption. Each node has two network interfaces: • the primary 1 Gb/2.5 Gb port that will remain on the main LAN for user traffic • a dedicated 10 Gb card reserved exclusively for inter-node traffic and for talking to a Synology NAS. That 10 Gb backplane needs to be the path for corosync traffic, VM replication and storage I/O so bandwidth is never a bottleneck. Your work will cover the clean installation of Proxmox VE, creation of the ...

    I’m looking for a specialist to run a full health-check on my Local Area Network. The priority is to verify that everything works as intended and to pinpoint any performance bottlenecks that might slow users down. Security is being handled separately, so your focus will be strictly on functionality and performance. The job involves testing end-to-end connectivity, measuring throughput and latency at peak and off-peak times, and confirming that current configurations on switches, routers, and access points align with best practices. I expect you to use industry-standard network diagnostic tools—think Wireshark, iPerf, or SolarWinds—but you’re free to bring in any utilities you trust as long as the results are clearly documented.

    Enable Panasonic SIP on FortiGate -- 2
    Končící left
    Ověřený

    My Panasonic Ns500 PBX sits on but cannot “see” the rest of my network. Everything else flows through a FortiGate 60F firewall, a FortiSwitch 424E-Fiber core, and a FortiSwitch 124F-FPOE at the edge.

What I already know • The PBX will run pure SIP. • Dedicated VoIP rules on the FortiGate are required; simple, generic access is not enough. What I need from you • Review the current FortiGate policy set, VLAN layout, and switch port profiles. • Create or adjust firewall rules, NAT, and any SIP ALG or helper settings so that SIP registration, signalling, and RTP streams pass without one-way audio or dropped calls. • Tag or untag the appropriate swi...
