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.
