/etc/ipnat.conf:
rdr rl0 0/0 port 9541 -> 192.168.0.2 port 9541 tcp
rdr rl0 0/0 port 9542 -> 192.168.0.2 port 9542 udp

somewhere on top of file (before "map").

Also you need something like this in your /etc/ipf.rules:

pass in quick on rl0 proto tcp from any to 192.168.0.2/32 port = 9541 keep state
pass in quick on rl0 proto udp from any to 192.168.0.2/32 port = 9542 keep state
