One possible way for 4.8-STABLE:

sysctl net.inet.ip.fw.one_pass=0

pipes 1,2,3,4 descriptions
add 100 skipto 30000 ip from any to any out
add 200 pipe 1 ip from 192.168.0.0/24 to any in recv eth1
add 200 pipe 2 ip from net2 to any in recv eth1
add 200 pipe 3 ip from net3 to any in recv eth1
add 200 pipe 4 ip from net4 to any in recv eth1
add 300 divert 300 ip from any to NATIP in
....
some rules to enable traffic
....
add 29900 deny log ip from any to any in
....
some rules to enable traffic
....
add 50000 divert 30000 ip from 192.168.0.0/24 to any out
add 50100 allow ip from NATIP to any out

and lounch
natd -a NATIP -i 300 -o 30000 -d
Where NATIP - some properly routable address

Sorry, not tested in 5.X
