Anscheinend wird keine Route gesetzt f\u00fcr die OPNsense selber, unter System -> Gateways -> Configuration erstellt man erstmal einen Gateway mit der LAN-Ipadresse.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Danach erstellt man eine Route mit dem soeben erstellten Gateway unter System -> Routes -> Configuration <\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Nicht vergessen bei Gateway und Router erstellen den Apply Button zu klicken. Ein anschlie\u00dfender ping zeigt uns das die Firewall selber jetzt das Remotenetz erreicht,<\/p>\n\n\n\n
