Hello Daniel, Make sure the configuration is consistent on all members on the cluster.
Do on the firs node : vim /usr/local/pf/conf/networks.conf (Make sure the VIP IP address is used for the gateway and DNS ) /usr/local/pf/bin/pfcmd configreload hard /usr/local/pf/bin/cluster/node/sync --as-master Then on node 2 and node 3: /usr/local/pf/bin/pfcmd configreload hard /usr/local/pf/bin/pfcmd service pf restart 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 Apr 30, 2024, at 11:19 AM, Daniel Zook via PacketFence-users > <packetfence-users@lists.sourceforge.net> wrote: > > I have a working packetfence cluster and everything seems to be setup and > working fine except that when a guest connects on the Registration VLAN, DNS > fails.
