hi. My office pfsense happily works with an IPv6 tunnel since months. right now I'm preparing a new server in my lab, and it's running pfSense 2.2.4. I don't have IPv6 enabled on this new box, nor DHCP of any kind (relay/server), nevertheless when it's running my client DHCPv6 gets crazy and keeps looping, even if it receives a lease. If I shut down the second pfSense everything returns to normality. It's not the first time it happens to me, when there's a second pfSense in LAN (even if the second pfSense has a fixed IP in another subnet) the network misbehaves.
What could it be? I'm attaching here a log of the DHCP client. P.S. pfSense is not acting as a DHCPv6 but just as RA This is the log of my client's dhcp Aug 6 13:46:12 dharma dbus[895]: [system] Successfully activated service 'org.freedesktop.nm_dispatcher' Aug 6 13:46:12 dharma nm-dispatcher: Dispatching action 'dhcp6-change' for wlan0 Aug 6 13:46:12 dharma systemd[1]: Started Network Manager Script Dispatcher Service.
