Mobile VPN routing to local network

Zottelmann

Hi there,

I have a strange problem routing through a mobile IPsec VPN on the Pfsense. A connection with the firewall comes up without any further problems. I can connect to networks connected via site-to-site, but I can't connect to the local network running on the Pfsense.

Attached is the log for the P2 tunnel, which also transmits the correct networks.
Strangely enough, I can't get into the 172.31.0.0/20 network.

On the other hand, Windows only shows me the following routes:

0.0.0.0       0.0.0.0           Auf Verbindung      172.31.5.254     26
172.31.5.254  255.255.255.255   Auf Verbindung      172.31.5.254    281
224.0.0.0     240.0.0.0         Auf Verbindung      172.31.5.254     26

Does anyone here know what the problem could be? Thank you in advance.
