Does your kernel have 'options IPFIREWALL_FORWARD' (if this is
needed for 8.1, I still run at 7.x)?
Else try the rule like this:
ipfw add 100 fwd 127.0.0.1 ip4 from me to any 1234 out via wlan0
or:
ipfw add 100 fwd 127.0.0.1 tcp from me to any 1234 out via wlan0
The fwd rule does only match the packets which match the rule 'ip4
from me to any 1234 out via wlan0' (me = alias for local IP
addresses), so they will be directed to 127.0.0.1 on the same
destination port. Other packets not for destination port 1234 will
just go out as usual.
