Advanced Routing over an IPSec Connection

What would be the best way to reach (network C) from (network A)?  What routes to i need to realize to get it to work?

Sorry for the cheap artwork  

(network A)  ASL  IPSec Connection  ASL  (network B)  Router  (network C) 

The ASL in (network A) knows nothing about where (network C) is.
The ASL in (network B) knows that he can reach (network C)  over the router in (network B).
The Router in (network B) knows that he can reach (network A) over the ASL in (network B).  

my thought is to add a static route on the ASL in (network A) for (network C) to the Router in (network B).

A major point is that NO NAT can take place between (network A)  and (network C) 

Current VPN Route:

217.5.98.15 dev ppp0  scope link 
217.5.98.15 dev ipsec0  proto kernel  scope link  src (dynamic IP) 
(network A) dev eth0  scope link 
(network B) via 217.5.98.15 dev ipsec0
 
Somehow I think something is missing like:
(network C) via Router (network B) via 217.5.98.15 dev ipsec0

err?? I am making it more complicated than it is eh??

Thx.
