Hi,
you are right and this is a dup of bug 1767283 which I already fixed in Cosmic
and have a backport for Bionic ongoing right now.
Closing this as Dup.

Title:
netcat-openbsd does not allow setting source port
Status in netcat-openbsd package in Ubuntu:
New
Bug description:
When connecting to a remote host, both the command-line help and man-
page state that specifying `-p` will set the local port number.
However, when I actually attempt to do it, only the usage text is
printed:
$ nc.openbsd -p 12345 localhost 12345
usage: nc [-46CDdFhklNnrStUuvZz] [-I length] [-i interval] [-M ttl]
[-m minttl] [-O length] [-P proxy_username] [-p source_port]
[-q seconds] [-s source] [-T keyword] [-V rtable] [-W recvlimit] [-w
timeout]
[-X proxy_protocol] [-x proxy_address[:port]] [destination] [port]
This appears to be caused by an erroneous check on line 541 of
netcat.c, introduced by `misc-failures-and-features.patch`. If I
remove the check or undo the patch completely, the source port is set
correctly, but remains bound after I close the connection. Meanwhile,
netcat-traditional works as expected.
