[c-nsp] routing through fwsm

Is there a trick to routing through a FWSM to non-directly connected networks?

My network looks like:

db-network (10.2.70.0/24)
   |
fwsm
   |
sj-nms-network (10.2.10.0/23) -- sj-vpn (10.2.10.12) == nl-vpn

On the other side of the vpn is 10.4.0.0/16 (nl).  The vpn box there has 
directly connected interfaces to the other networks.

Routing between the two nms networks works.  Routing between the sj-nms and 
networks behind the nl-vpn works.  Where I'm stuck is getting the fwsm to route.

I have a route defined.  If I try to connect from 10.4.70.20 to 10.2.70.103, 
the fwsm logs :

Mar  3 16:22:58 fwsm1 %FWSM-3-106010: Deny inbound tcp src 
nms:10.4.70.20/32770 dst db:10.2.70.103/22

but not against a specific ACL. If I go the other way around, I don't get any 
errors and tcpdump on sj-vpn doesn't show any traffic either.

Any ideas?
