Sieht so aus als würde alles nur auf LAN und DMZ landen

"Ich nehme an, re0 ist das DMZ-Interface."

Meinst du auf der Weboberfläche: Interfaces: Diagnostics: Netstat, wenn ja welche Infos brauchst du?


SSH-Zugriff auf OPNsense habe ich bislang nicht aktiviert...wenn es aber nur so geht, kann ich das auch machen

Müsste hier eigentlich die Mac-Adressse des hosts und nicht die Mac-Adresse des LAN interface auftauchen?

Die Regel habe ich nach der Installation nicht/nie angefasst....

Hallo,
ich kann aus dem LAN nicht auf die DMZ zugreifen und kann auch nach längerem Suchen und Probieren nicht feststellen wo etwas falsch läuft.

Firewall LAN ; Default allow LAN to any rule
Firewall DMZ ; ping any to any (Testzwecke)


Ping
lan -> lan ok

Irgendwie kommt beim Ping aus dem LAN in die DMZ kein Reply, aber ich kann nicht erkennen woran das liegt. Es scheint kein Firewall-Problem zu sein und der Host reagiert beim Ping aus dem Wireguard-Netz.......

Wo liegt der Fehler?

I encounter the same problem did u find any solution?

Hello everyone,


As shown in the network diagram, i am trying to access the web interface of the LTE modem. However, I can't figure out how to route the request. Accessing the web interface from local LAN is working, although modem IP is outside LAN adresspool. Could you please help me with some advice how to route this without adding another managed route in ZeroTier.

Thanks Stephan
