Description of problem:
It is possible to specify whatever name instead of the "toaddr" option and firewalld is accepting it, but skips the value.
Version-Release number of selected component (if applicable):
I was able to reproduce it on all RHEL 7.x versions.
Type whatever word instead of toaddr option.
Steps to Reproduce:
$ cat /etc/redhat-release
Red Hat Enterprise Linux Workstation release 7.5 (Maipo)
$ firewall-cmd --add-forward-port=port=1213:proto=tcp:toport=22:TOWHATEVER=10.10.10.1
$ firewall-cmd --list-all
interfaces: eth0 ens3 ens10 team0
services: dhcpv6-client ssh
forward-ports: port=1213:proto=tcp:toport=22:toaddr= <---
The command is successful and the toaddr value is missing
Some error message like
firewall-cmd: invalid parameter TOWHATEVER
Please let me know in case any further details are needed.
This has been fixed upstream. Recent versions of firewalld are much better at propagating errors to the UIs/user.
# firewall-cmd --add-forward-port=port=1213:proto=tcp:toport=22:TOWHATEVER=10.10.10.1
Error: INVALID_FORWARD: invalid forward port arg 'TOWHATEVER'
