RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
It is possible to specify whatever name instead of the "toaddr" option and firewalld is accepting it, but skips the value.
--add-forward-port=port=portid[-portid]:proto=protocol[:toport=portid[-portid]][:toaddr=address[/mask]] [--timeout=seconds]
Version-Release number of selected component (if applicable):
I was able to reproduce it on all RHEL 7.x versions.
How reproducible:
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
success
$ firewall-cmd --list-all
public (active)
target: default
icmp-block-inversion: no
interfaces: eth0 ens3 ens10 team0
sources:
services: dhcpv6-client ssh
ports: 22/tcp
protocols:
masquerade: no
forward-ports: port=1213:proto=tcp:toport=22:toaddr= <---
source-ports:
icmp-blocks: echo-request
rich rules:
Actual results:
The command is successful and the toaddr value is missing
Expected results:
Some error message like
firewall-cmd: invalid parameter TOWHATEVER
Please let me know in case any further details are needed.
Thank you
Fani
Additional info:
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'
