Assuming you've configured your tunnel(s) correctly, both firewalls
should have routes to the corresponding side; i.e. your firewall will
have a static route for the 10.0.43.0/24 network and packets from your
LAN should automatically go across. For example, a "netstat -rnf encap"
on my office firewall shows:

[EMAIL PROTECTED] ~> netstat -rnf encap
Routing tables

Encap:
Source             Port  Destination        Port  Proto
SA(Address/Proto/Type/Direction)
130.57.44.64/27     0     192.168.168.30/32  0     0
206.14.107.83/50/use/in
130.57.44.64/27     0     192.168.168.32/32  0     0

130.57.44.64/27     0     192.168.169.2/32   0     0
208.16.27.92/50/use/in

The boxes at 192.168.168.30/.32/.50 and 192.168.169.2 reach the
130.57.44.64/27 network over the VPN tunnel. Check out your SAs and see
what flows you actually have configured.
