Proxmox - pfSense einrichten



  • Da ich mit dem Gedanken spielen, alles was hier an Servern läuft aufzulösen und es auf dem Proxmox laufen zu lassen, fangen wir heute Nachmittag mal an 🙂

    Netzwerk Anfang

    Der Internetanschluss fängt mit einer Fritzbox 6490 an (meine 😉 ). Da ich denen nicht besonders traue, kommt danach meine Firewall. Lange Zeit habe ich IPFire eingesetzt, seit dem ich mal IPv6 testen wollte, bin ich auf pfSense gewechselt. Somit muss das mal als erstes auf die Kiste 🙂

    Installation Hardware

    Für die Installation einer pfSense auf dem Proxmox braucht man zwei zusätzliche Netzwerkkarten. Schublade auf, da liegen noch welche rum. Müssten von meinen ersten Versuchen mit IPFire über sein 😉 Ab damit in den Proxmox.

    Damit haben wir jetzt zwei zusätzliche Netzwerkkarten im Proxmox. Nach Anleitung vorgegangen und hier ist das Ergebnis.

    Danach muss noch neugestartet werden!

    Installation pfSense

    Ok, ich erspare mir das Abtippen der sehr guten Anleitung.

    https://docs.netgate.com/pfsense/en/latest/virtualization/virtualizing-pfsense-with-proxmox.html

    Hier nur ein paar Bilder!

    Oh, ein Fehler. Da habe ich doch versehentlich das Image auf dem falschen Laufwerk installiert (NFS). Schnell mal verschieben.

    Gut das ist erledigt.

    Testlauf

    Dann wollen wir das mal ein paar Tage beobachten. Und das hier unbedingt machen, davor hatte ich eine grottenschlechte Verbindung.

    To disable hardware checksum offload, navigate under System > Advanced and select Networking tab. Under Networking Interfaces section check the Disable hardware checksum offload and click save. Reboot will be required after this step.

    Zum Schluß, erst mal aufräumen 🙂

  • Schade, der Netzwerkdurchsatz ist nicht optimal 😞

  • Ok, das mit den uralten Karten, die hier rumlagen, war dann doch nicht so eine tolle Idee. Mit beiden Karten bekomme ich keine vernünftigen Geschwindigkeiten hin.

    Heute kam noch eine Realtek-Karte, die war eigentlich für Orange gedacht, aber jetzt musste sie erst mal für die Fehlersuche herhalten. Aktuell läuft die Realtek als WAN und ein USB-C to LAN-Adapter als LAN mit ordentlicher Leistung.

    Da muss ich noch mal über Netzwerkkarten nachdenken, da muss was vernünftiges her. Im Moment zum Testen reicht es erst mal 😉



  • Gut, nachdem heute eine Netzwerkkarte mit zwei LAN.Schnittstellen gekommen ist baue ich das mal so um, wie ich es gerne hätte.

    So sieht das jetzt im Proxmox aus.

    Meine Rules rein gemacht und meine virtualisierte pfSense auf der Proxmox ist einsatzbereit 🙂 Bei der ganzen Testerei konnte ich auch die Backups gut testen. Wenn dann mal nichts mehr ging ein Klick aufs Backup, danach lief sie wieder.

    Damit ist das Thema hier durch. So als kleines Fazit, achtet auf die Netzwerkkarten. Da muss was aktuelles und leistungsfähiges rein. Sonst macht die Kiste hinterher zu Hause einfach keinen Spaß! Und darum geht es ja, es soll Spaß machen 🙂



  • Als kleine Ergänzung. Von einer VM aus zum Hauptrechner.
