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.
+++ This bug was initially created as a clone of Bug #2229935 +++
Description of problem:
After enabling IP forward functionality, VMs can only ping each other but not SSH or do iperf3 tests. This happens on both ARM64 RHEL 8.9 and RHEL 9.3.
Version-Release number of selected component (if applicable):
4.18.0-506.el8.aarch64
5.14.0-347.el9.aarch64
How reproducible:
100%
Steps to Reproduce:
Polarion test case - https://polarion.engineering.redhat.com/polarion/#/project/RHELVIRT/workitem?id=RHEL-196234
OR follow steps in previously reported bug -
https://bugzilla.redhat.com/show_bug.cgi?id=1898280#c6
SSH from 'sender' VM to 'receiver' VM, or vice versa. Use iperf3 to send/receive traffic.
Actual results:
Neither SSH or iperf3 can find the destination address. But ping is okay (less than 10ms delay).
Expected results:
Should be able to SSH and do iperf3
Additional info:
Issue does not present on x86_64 RHEL 8.9 or 9.3.
