--- Comment #3 from Lutz Donnerhacke <donner at FreeBSD.org> ---
That's a parsing problem.
# ipfw add 7110 fwd 0.0.0.0,8000 tcp from 'table(5)' to any dst-port
80,8000,8080
07110 fwd tablearg,8000 tcp from table(5) to any 80,8000,8080
# ipfw add 7110 fwd tablearg tcp from 'table(5)' to any dst-port 80,8000,8080
07110 fwd tablearg tcp from table(5) to any 80,8000,8080
Probably this case was never tested well, because the port is only used when
the forward address is a locally bounded one. (According to the man page.)
Thank you for notifying this.
