IPSec VPN can´t reach network

Hey there,

I´ve configured an IPSec Remote Access.I can connect the Client to the VPN an I also able to ping the firewall over the VPN. But I´m not able to ping a Host in the VPN Network. I´m also able to reach the Internet over the VPN tunnel.

If I do an tcpdump I can see, the Host in the VPN Network is answering the ping from the client.

SFV2C4MSP_SO01_SFOS 18.0.4 MR-4# tcpdump 'host 172.19.20.100' and 'host 10.0.1.20'

10.0.1.20 is a Server in the VPN Network which I can´t reach, 172.19.20.100 is the VPN Client.

On the Client I get a simple timeout message.

This is my VPN Config:

I also tried to create a any/any Firewall rule to check if I failed a firewall rule but I didn´t change anything,

Any Idea how I can get this Work? Thanks!
