Last night my tunnel to seattle seems to have stopped working in the middle of the night. I can ping the IPv4 endpoint, but not the IPv6 server IP. Nothing has changed on my config, nor my internet service. I'm using pfsense 2.4.4p2. I've tried taking the interface down/up, but no difference. Is there anything up with the Seattle tunnel endpoint?
Thanks in advance! Here's some information. If you need something else, please let me know.
