Suddenly lost web traffic and some inbound NATs stopped

[Taomyn]

I woke up this morning to find I had no access to websites, and further investigation shows my inbound NATs are not working. I think it's related to this, but I can't work out where to look as the message is incomplete:

Any ideas how I can find what "<!DOCTYPE[/size][size=78%]" is referring to?[/size]

Update, I managed to fix it by disabling the option "Allow IPv6" on the Firewall, Settings, Advanced screen.


No idea why this would suddenly happen, I don't use IPv6 as it's mostly broken for me and so anywhere it can be enabled on the interfaces they remain disabled.


If I can provide logs for investigation let me know which ones.

Hi, are you on OPNsense 18.1.5 too?

Bad bogons for IPv6.

Run this:

# /usr/local/etc/rc.update_bogons


Cheers,
