Routing packets through VPN IPSec

I have a IPSec VPN beetween PRT661H-63 (192.168.2.0/24) and a Zywall 2WG (10.0.0.0/24).
I have a Linux Firewall beetween my Zywall 2WG and my LAN (192.168.1.0/24).

How can i forward tcp packets from (192.168.2.0/24)to my LAN (192.168.1.0/24)?

I tried to aply a policy route with no luck.
There is no packet information arriving in the Wan NIC (Eth1) of my Linux Server.
