Description
Setup:
WAN - IPv4 PPPoE via re1, IPv6 via SLAAC.
Expected result: Stable IPv6 connectivity
Actual result:
When booting, pfsense brings up PPPoE wan, using pppoe1.
ipv6 RA is recieved from ISP.
IPv6 Default gateway is then set to fe80::f2f7:55ff:fe55:d300%re1
The problem here is the %re1 - this is the parent interface, and not the PPPoE link.
While this is in use as default gateway, there is no WAN or LAN ipv6 connectivity.
Solution:
SSH to pfsense
route del -inet6 default
route add -inet6 default fe80::f2f7:55ff:fe55:d300%pppoe1
This solution is only temporary until either a new RA is recieved, or the system reboots, or the PPPoE link reconnects.
This has happened since around 2.2 era, on all types of hardware.
