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:
If you want to run ftp server on different port, you have to tell nf_conntrack_ftp module to track connection on that port. iptables init script is not able to load module with parameter correctly.
Version-Release number of selected component (if applicable):
iptables-1.4.7-4.el6.x86_64
How reproducible:
always
Steps to Reproduce:
1. modify /etc/sysconfig/iptables-config file, add ports=9876 parameter to nf_conntrack_ftp module. Line should look similar to this one:
IPTABLES_MODULES="nf_conntrack_netbios_ns nf_conntrack_ftp ports=9876"
2. re/start iptables (service iptables restart)
Actual results:
# service iptables restart
iptables: Flushing firewall rules: [ OK ]
iptables: Setting chains to policy ACCEPT: mangle nat filte[ OK ]
iptables: Unloading modules: [ OK ]
iptables: Applying firewall rules: [ OK ]
iptables: Loading additional modules: nf_conntrack_netbios_[FAILED]nntrack_ftp ports=9876
Expected results:
iptables: Flushing firewall rules: [ OK ]
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Unloading modules: [ OK ]
iptables: Applying firewall rules: [ OK ]
iptables: Loading additional modules: nf_conntrack_netbios_[ OK ]nntrack_ftp
Please create a new conf file in /etc/modprobe.d and add the option for the module there:
/etc/modprobe.d/nf.conf
options nf_conntrack_ftp ports=9876
IPTABLES_MODULES only contains module names, please have a look at the documentation:
# Load additional iptables modules (nat helpers)
# Default: -none-
# Space separated list of nat helpers (e.g. 'ip_nat_ftp ip_nat_irc'), which
# are loaded after the firewall rules are applied. Options for the helpers are
# stored in /etc/modprobe.conf.
Closing as not a bug.
