Routing Between several IPSec Site-to-Site Tunnels

Hi,

following Scenario:

Site A = XG with static Public IP 

Site B = Homeoffice 1: FritzBox(dynamic) --> OpenWRT(forIPsec S2S) --> HO1 Network

Site C = Homeoffice 1: FritzBox(dynamic) --> OpenWRT(forIPsec S2S) --> HO2 Network

I have sucessfully connected Site B&C to Site A

Now i have the problem that Site B and C are unable to communicate.

I thougt i can create a second tunnel on each openwrt to the Sophos, to route everything over there but it won't work. 

is this even possible?

Regards
