Routing between remote networks not working

Hello,
Currently I have 3 LANs. MainLAN, RemoteLAN1 and RemoteLAN2. Those LANs have DLink DIR-640L routers and are connected with IPSec. Here is the configuration.

MainLAN (DIR-640L router)
IP subnet: 10.1.1.x (255.255.255.0)
Default Gateway: 10.1.1.1

RemoteLAN1 (DIR-640L router)
IP subnet: 10.2.1.x (255.255.255.0)
Default Gateway: 10.2.1.1
Connected to MainLAN through IPSec

RemoteLAN2 (DIR-640L router)
IP subnet: 10.3.1.x (255.255.255.0)
Default Gateway: 10.3.1.1
Connected to MainLAN through IPSec

When IPSec tunnel is UP:

-Computers in MainLAN can ping computers in RemoteLAN1 and viceversa
-Computers in MainLAN can ping computers in RemoteLAN2 and viceversa
-Problem: Computers in RemoteLAN1 CANNOT ping computers in RemoteLan2 and viceversa

What can I be doing wrong or what else do I need to do so computers in remote lans can see each other?

Thanks
