I have two LANs connected with a VPN

LAN1:192.168.0.0/24 <=> VPN:192.168.2.0/24 <=> LAN2:192.168.10.0/24

The two routers (one on each side of VPN) are running on Debian Linux and Ipv4 forwarding is set to 1.

I have set static routes :
On LAN1:
On the router : 192.168.10.0/24 via 192.168.2.1 (other side of the VPN)
On clients : 192.168.10.0/24 via 192.168.0.202 (router IP)

On LAN2 :
On the router : 192.168.0.0/24 via 192.168.2.2
On clients : 192.168.0.0/24 via 192.168.10.10 (router IP)

From routers, I can ping other router local ip
FRom LAN1 I can ping router 2
But from LAN2 ou router 2 I CANNOT ping LAN1, what may be going wrong ? Why can I only ping from only one side ?

TThanks for your suggestions
