Hello! My pfsense box has seemingly decided to attain sentience and its first action was to spite its master. I had a pending update for 2.7.0-RELEASE but now the system is running 2.7.0 - seemingly having updated itself. The problem is that there seems to be a problem retrieving an IP from my ISPs DHCP6 server on this version.

My ISP has double-checked for me, and they are handing out an IP that should look like 2a05:f6c7:8321::/48 and this is consistent with what I expect it to look like.

Going through my pfsense settings, nothing seems to have changed from the settings my ISP require for IPv6 to work.

My pfsense box is attached directly to their fiber modem, communicating on vlan 101

This is set up as follows (these links may not work if you use IPv6) WAN interfacehttps://u.drkt.eu/9YLi99.png LAN interface u.drkt.eu/8KxPEJ.png Interface Assignments u.drkt.eu/XXJTci.png VLAN 101 u.drkt.eu/eM72PE.png

If I run tcpdump and then restart the gateway, I get these packets

tcpdump -ni alc0.101 -c 1000 -U -w - '((ip6)) and ((not vlan))'
