Mikrotik L2TP IPSEC kein Zugriff aufs Lan aber auf Router und per VPN angebundene Standorte

Hallo,

ich habe zwei Standorte per IPSec angebunden, nun wollte ich per L2TP IPSec eine RoadWarrior Verbindung herstellen, dies funktioniert aus soweit. Ich habe aber leider kein Zugriff auf das Lan. Ping zum Router und vom Router gehen. Auch der Zugriff auf die per IPSec eingebundenen Netze.
Wie in der Konfig zu sehen ist, werden IP-Adressen aus dem Lan-Netz an die Clients verteilt. Für den DHCP Server habe ich dementsprechend fürs Lan den Bereich begrenzt und einen extra Pool für L2TP angelegt. Auch wenn ich in der L2TP Konfig den normalen Lan Pool angebe bekomme ich keine Verbindung ins Lan.
Proxy-ARP ist in der Bridge aktiviert. So steht es in dem Beispiel von Mikrotik und auf diversen anderen Seiten.

Ich habe auch zum testen alle Drop-Regeln deaktiviert, auch so war leider kein Ping auf die Geräte im Lan möglich.
Die Geräte im Lan haben keine Firewall aktiv und sind auch aus den anderen Standortverbindungen zu erreichen.

Hier die Konfig.:

Bist du hiernach vorgegangen ??
Scheitern am IPsec VPN mit MikroTik

Mögliche Fehler:

Proxy ARP aktiviert ?
L2TP VPN Client IP Adressen vergessen in der MT Firewall einzutragen das sie vom NAT (Adress Translation) ausgenommen sind ?
Wenn du Windows Endgeräte anpingst ggf. ICMP (Ping) in der Firewall freigeben was dort generell gesperrt ist.
Stimmen die Rückrouten ? Sprich haben die angepingten Endgeräte einen Gateway Eintrag ?

Hey, danke für die Antwort.

Zitat von @aqui:

Bist du hiernach vorgegangen ??

Mögliche Fehler:

Proxy ARP aktiviert ?

Proxy ARP ist in der Bridge aktiviert.

* L2TP VPN Client IP Adressen vergessen in der MT Firewall einzutragen das sie vom NAT (Adress Translation) ausgenommen sind ?

Die IP ist ja aus dem LAN Netz, auch wenn ich sie in die Firewall eintrage das sie vom NAT ausgenommen sind geht es nicht.

* Wenn du Windows Endgeräte anpingst ggf. ICMP (Ping) in der Firewall freigeben was dort generell gesperrt ist.

Firewall ist wie oben beschrieben deaktiviert. Außerdem sind die Endgeräte von den anderen Standorten anpingbar.

* Stimmen die Rückrouten ? Sprich haben die angepingten Endgeräte einen Gateway Eintrag ?

Ja die Geräte haben einen Gateway Eintrag. Der ganze Traffic soll auch über VPN geroutet werden, das klappt auch. Genauso komme ich auf die Geräte an den anderen Standorten. Nur nicht an dem Standort wo ich mich einwähle.

Gruß

Das hattest du auch beachtet ?
Mikrotik kein Zugriff über VPN direkt auf Router

Ja, aber das bringt nichts. ich komme ja so schon auf den Router, nur nicht ins Lan. Auch wenn ich input und forward alles erlaube kann ich nicht auf Clients im Lan zugreifen.

Ich habe auch schon mal einen neuen Pool angelegt mit einem anderen Netz. Ich bekomme beim Verbinden eine IP aus dem Pool, wenn ich dann eine Regel erstelle für Input komme ich auch auf den Router aus dem Netz. Ich komme auch in Internet, aber nicht auf die Geräte im Lan...

Gruß

Zum Verifizieren mal einen kleinen Testaufbau geamacht:

2 Mikrotiks mit einem Standort IPsec VPN sowie GRE Tunnel und dynamischen Routing liefen schon. Standard Firewall aus der Default Konfig. Auf dem Roten dann einfach nur einen L2TP Server hinzugefügt.

Konfig der beiden Geräte:

Fazit:
Funktioniert fehlerlos und ohne Probleme. Alle Endgeräte in den jeweiligen lokalen LANs sind vom L2TP Client völlig problemlos ping- und erreichbar !
Dein Verhalten lässt sich absolut nicht nachvollziehen !!

Wie man in zeile 60 sieht ist das IN Interface die L2TP Verbindung und Out die Bridge, so soll es doch auch sein?!

Gruß und danke

Muss aber de facto an deiner Konfig oder einer falschen FW Regel liegen. Wie gesagt...in einer Standard Konfig mit typischer Internet Firewall lässt sich der Fehler nicht nachvollziehen.
Das o.a. Setup rennt fehlerlos !
Ggf. deaktivierst du temporär mal schrittweise deine Regeln mit Ausnahme der wichtigsten und checkst welche da den VPN Traffic blockt ?!

Hey,
habe schon mal alle Drop Regeln deaktiviert.
Wenn ich auf dem Server mit Tcpdump schaue kommen die Anfragen auch an.

Ich werde es erstmal anders lösen bis ich die Zeit habe es nochmal in Ruhe nachzustellen. Ich erreiche auch über die Verbindung die eingerichteten VLAN´s, so wie es momentan auch sein soll.
Nur halt aus dem Lan scheinen die Pakete wieder über die PPPOE Verbindung zu gehen. Habe jetzt ein extra Netz erstellt und damit läuft es jetzt erstmal.

Danke dir für deine Hilfe ;)

Gruß
