Hallo!

Ich habe immer wieder die folgende Fehlermeldung im Ereignisprotokoll meines
ISA2004-Servers und weiß nicht so richtig, was ich dagegen machen kann:

Ich habe einen ISA2004 mit SP1 auf einem Win2003-Server mit SP1. Der ISA hat
zwei Netzwerkkarten, eine (LAN) für den internen Verkehr (192.168.2.0) und
eine (WAN) für DSL mit der IP 192.168.3.1. Desweiteren ist eine
DFÜ-Verbindung eingerichtet für die DSL-Einwahl (mit fester IP).Weiterhin
habe ich OpenVPN auf dem Server installiert, so dass also noch eine weitere
Netzwerkkarte installiert ist. Diese arbeitet im 192.168.200.0-Netz
Ich bekomme in regelmäßigen Abständen die folgenden Fehlermeldungen:

---- Fehler 1-----
ISA Server detected routes through adapter LAN that do not correlate with
the network element to which this adapter belongs. For best practice, the
address range of an ISA Server network should match the address ranges
routable through the associated network adapter as defined in the routing
table. Otherwise valid packets may be dropped as spoofed. (This alert may
occur momentarily when you create a remote site network. You may safely
ignore this message if it does not reoccur.) The address ranges in conflict
are:
0.0.0.1-126.255.255.255;128.0.0.0-192.168.1.255;192.168.4.0-192.168.199.255;
192.168.201.0-192.168.249.255;192.168.250.255-223.255.255.255;240.0.0.0-255.
255.255.254;.

240.0.0.0-255.255.255.254;.
------------------

Das sind also wohl alle Netzwerke, die es außer meinen eingerichteten gibt.
Wenn ich meine Routingtabelle anschaue, sieht die aber völlig in Ordnung
aus. Ich weiß also nicht, woher sich der ISA-Server jetzt die Routen holt.

Was kann ich da machen?
