ProjektHelp! Open VPN bridgen PC zu PC

[DaVeD]

Es geht darum zwei Private Netze über OpenVPN zu verbinden, das ganze soll gebridged laufen so dass die Windows Freigaben funktionieren, und auch alle broadcasts beim Client ankommen.

Das erste (SERVER) Netz arbeited mit:

Netz 192.168.0.0

VPN Server 192.168.0.69

Router 192.168.0.1

Das zweite (Clientnetz) mit:

Netz 192.168.2.0

VPN Client 192.168.2.2

Router 192.168.2.100

In beiden Routern ist der Port 1194 für eingang und ausgang frei.

Also hab ich hier folgendes server.ovpn

Jetzt hab ich die den Ethernetcontroller des Servers mit dem VPN-Tap gebridged per rechte maustaste überbrücken.

Jetzt müsste doch normalerweise die Verbindung so von statten gehen das der Client der in seinem Privaten Netz die 192.168.2.2 hat vom Server eine Adresse im Servernetz zugewiesen bekommt (230-250) also wahrscheinlich die 192.168.0.231. Warum passiert da nix?

Der Client bekommt als letzt meldung immer nur:

Sun Apr 16 16:36:51 2006 UDPv4 link local: [undef]

Sun Apr 16 16:36:51 2006 UDPv4 link remote: 84.166.216.181:1194

Ich frickel da jetzt schon Tage ohne unterlass dran rum, Fakt ist das es alles in meiner Doku funktionieren soll allerdings tuts ds nicht und bricht mir nochs Genick....

Plz help

[..::rEnE::..]

Warum soll das nicht mit Routing funktionieren ???

Wenn das Routing richtig konfigueriert ist, dann laufen da auch alle Windows-Freigaben ganz normal...

gib mal in die Konsole "ROUTE PRINT" ein, dann erhälst du die Routing-Tabelle... Du musst dann nur eventuell, um Zugriff in ein anderes IP-Netz zu bekommen, die passenden Routen anlegen. Bei OpenVPN geht dies direkt im .ovpn-File...
