Hello Daniel, Iptables is needed in PacketFence for firewall and also routing.
If you turn off iptables, you will lose the filtering part but also any registration and isolation routing. If you don’t have a registration and isolation network then you are fine. You can do: systemctl disable packetfence-iptables --now systemctl mask packetfence-iptables Thanks, Ludovic Zammit Product Support Engineer Principal Lead Cell: +1.613.670.8432 Akamai Technologies - Inverse 145 Broadway Cambridge, MA 02142 Connect with Us: <https://community.akamai.com/> <http://blogs.akamai.com/> <https://twitter.com/akamai> <http://www.facebook.com/AkamaiTechnologies> <http://www.linkedin.com/company/akamai-technologies> <http://www.youtube.com/user/akamaitechnologies?feature=results_main> > On May 30, 2024, at 3:18 PM, Daniel Zook via PacketFence-users > <packetfence-users@lists.sourceforge.net> wrote: > > I set up a 3-node cluster environment and everything is working as expected, > *EXCEPT* that when the IPTables service is running the cluster fails to > respond to DNS requests.
