IPSEC site to site VPN via Preshared key

I have installed 2 set of AGS9.0 firewal. Firewal 1,Lan IP segment 192.168.0.0/24 and firewal 2 Lan Ip segment 192.168.2.0/24.

I have created IPSEC site to site VPN via Preshared key between these 2 firewal.

I can able to successfully establish the connection between two firewal.

Iam unable to do RDP from Lan segment (192.168.0.0/24) behind firewal 1 to the windows server located in Firewal 2 Lan segment 192.168.2.0/24.

However from Lan segment 192.168.2.0 I can able to RDP and connect the windows server located in segment 192.168.0.0/24. behind "Firewal 1"

Appreciate your help here to resolve this issue.
