OPNSense Adapter ipv6 Problems on Fiber

[Bytechanger]

Hi,

I´ve got fiber from my isp.
My configuration is, Fiber-->ISP-Modem<---->OPNSense at first, after Problems now
Fiber-->ISP-Modem<---->FritzBox<---->OPNSense.

My Problems are, after hours (or somtimes Minutes) my IPv6 get loss.
Somtimes it get´s back fast, somtimes it takes soooo long. IPv4 is there.

When I look at my syslog there a 2 things:

1) it seems, my adapter goes down/up sometimes?!
2) why there is an local ip that want to be forwarded?? "cannot forward src fe80"

Hej, this might be a known error and related to this bug: https://github.com/opnsense/core/issues/4338
This does not immediately solve your issue, but at least might give you an indication about the why .

I've plenty of IPv6 issues as well, I'm currently behind a FritzBox as well but I cannot even ping my FB via link local address, even though I can see the FW sending and returning ICMP packets in the FW log. I gave up and wait for a new release.

Thanks,

my additional problem seems, that my WAN interface go up/down after hours.
Than after hours up/down after minutes 30-50.
This seems to be a software problem, on old PPOE it works fine.

I have a similar problem (ipv6 stops working).  If I reboot OpnSense, ipv6 works for 4 minutes, then stops working. Reboot it again and it'll work (for another 4 minutes).  The command recommend on this bug report ("pluginctl -s radvd restart" reported here: https://github.com/opnsense/core/issues/4338) doesn't work for me.  I'm using v20.7.3 and my ISP is fiber (ISP -> ONT -> OpnSense).  When I say "not working" I mean I can "ping6 google.com" and that works for up to 4 minutes after a reboot.  After 4 minutes, 100% failure. I don't have the thread/URL handy, but I did recall seeing someone else (not sure if it was on this forum or elsewhere) indicate they had similar issues and moved back to 20.1.  I'm likely going to try that, but will not be able to for a few more days.
