  1. Non-optimal routing speeds with Proxmox 7

    Hey all, I'm in the process of setting up a Mikrotik CHR (Virtual Router) for routing 10Gb network traffic. However, testing with EXFOs has shown that, with random packet size, I am not getting anywhere near 10Gb/s (I'm getting around 6Gb/s average, should be closer to 8Gb/s). I've tried...

  11. SDN + netns: namespaces, bridging and VLANS

    Mainly, it would be fantastic if someone could give me a "here be dragons" on using Proxmox SDN with policy-based routing (i.e. multiple gateways with iproute2 tables + `ip rule`). I would like some more advanced networking (e.g. multiple NICs: i have will have 4 very soon). In configuring...

  15. [SOLVED] [WORKAROUND FOUND] Routing issues probably self-inflicted. Amateur needs help. Only for patient users.

  16. How to configure a vm for internet access?

    Hello. I'm trying to get my vm (puppy linux) connected to the internet. I'm currently using my wireless network card on my laptop (host), however I've realised that I cant bridge it to the VLAN (I believe it has something to do with multiple MAC addresses using the device).
