Fehlersuche bei IPsec VPN mit IKEv2
Ein half-managed IPsec-VPN ist wie ein Ochsenkarren mit Tieren aus verschiedenen Ställen und Treibern, die sich nicht kennen.
Natürlich geht die Reise meist gut, aber oft dauert es länger als gedacht, bis alles ineinander greift und zueinander passt.
Dieses Buch soll ein Reisebegleiter sein und über die größten Klippen hinweg helfen.

About the Book
IPsec VPN sind dazu da, Daten sicher über unsichere Netze zu transportieren. Nahezu jeder Hersteller von Netzwerkgeräten bietet heutzutage IPsec-Funktionalität mit an. Also sollte es ein leichtes sein, mal eben ein IPsec-VPN zu einem Geschäftspartner über das Internet einzurichten.
Doch wenn es konkret wird, beginnt manchmal das Haareraufen, weil beide Partner verschiedene Geräte haben, deren Hersteller die Standards unterschiedlich interpretieren und verschiedene Begriffe für die gleichen Dinge oder die gleichen Begriffe für verschiedene Dinge verwenden.
Dazu kommt, dass jeder der Administratoren nur ein Teil des ganzen sieht und so nicht klar wird, wo das Problem liegt.
Dieses Buch soll ein Leitfaden sein, der hilft, die zugrundeliegenden Probleme bei nicht funktionierenden VPN schnell zu identifizieren und Abhilfe zu schaffen.
