auf einem LANCOM 1781VA-4G sind eine VDSL-Verbindung uns eine Mobilfunkverbindung eingerichtet. Die Namen der Gegenstellen sind allerdings manuell vergeben worden. Unser Problem ist, dass die Backup-Verbindung nicht aufgebaut wird, wenn DSL ausfällt. Mit einem Testgerät habe ich die Konfiguration auf ein Minimum verringert und bin nun auf die Ursache gestoßen - allerdings fehlt mir eine Erklärung.
Speziell zur Mobilfunkverbindung:
Ich bin bisher davon ausgegangen, dass der Name der Gegenstelle, die entsprechend unter /Setup/WAN/Dialup-Peers und /Setup/WAN/PPP verwendet wird, unabhängig vom Namen des Mobilfunkprofils unter /Setup/Interfaces/Mobile/Profiles ist. Auch LANconfig deutet keine derartige Abhängigkeit an. Konfiguriere ich den Router ausschließlich mit LTE - also ohne eine VDSL-Verbindung - funktioniert alles wie gewünscht. Es wird eine Internetverbindung zur Gegenstelle "LTE_T-MOBILE" mit dem Profil "T-MOBILE-SIM1" aufgebaut:

Ergänze ich nun noch eine VDSL-Verbindung und konfiguriere die Mobilfunk-Verbindung als Backup für's DSL, sieht die Konfiguration so aus

Ganz offensichtlich sucht der Router nun ein Mobilfunkprofil "LTE_T-MOBILE". Klar, das kann ich anlegen. Aber wo ist der Denkfehler? Müssen die Namen des Mobilfunkprofils und der Gegenstelle doch identisch sein? Warum geht das aber bei einer reinen Mobilfunkverbindung, ohne DSL?36 2021-08-08 14:05:27 KERN Fehler WWAN: Can not find profile 'LTE_T-MOBILE'.

Das Problem haben wir auf diversen 1781VA-4G mit der Version 10.34. Ich meine, dass wir es aber auch schon in früheren Versionen, wie z.B. der 10.12 hatten.
