This bug appears on 12.2 also.
Maybe example above is too complicated, below one is simpler.

route -4 add default your_gw
route -4 add -host 169.254.1.1 127.0.0.1
route -4 add -net 169.254.1.2/32 127.0.0.1
ipfw table 8 create type addr valtype ipv4
ipfw table 8 add 8.8.8.8 169.254.1.1
ipfw table 8 add 8.8.4.4 169.254.1.2
ipfw add 8 fwd tablearg ip from any to 'table(8)'


> ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes

Routing must be same for both destinations, why different?
