How did you configure IPv6 on interface igc0? Something is wrong with that.

[tiermutter]

Remember that radvd is located at Services/Router Advertisments. This configuration should also be taken into account for that interface.

[JoK]

Well, its stock, i did not change anything, IPV6 configuration type is, track interface...is that the problem?

[Patrick M. Hausen]

What are the actual IPv6 addresses and prefix lengths on WAN and LAN? What size of a prefix does your ISP give you?

You can obfuscate the lower 4 words of the addresses.

[JoK]

Not sure how I see this....

[Patrick M. Hausen]

Dashboard - interface widget. Or Interfaces > Overview.

[JoK]

Looks like i get a /56 from ISP and /64 from LAN...

[Patrick M. Hausen]

Which interface is igc0? You should not run router advertisements on WAN.

[JoK]

Igc0 is LAN

[Patrick M. Hausen]

Please post the output of "ifconfig igc0".

[JoK]

Hmm...how do i find that? Sorry, not much experince in this

[Patrick M. Hausen]

Login to your OPNsense via SSH, type "ifconfig igc0 <ENTER>" and copy and paste the output as text here.

[JoK]

Oh..I dont have any experience with that, any other way?

[Patrick M. Hausen]

No. Debugging things requires use of the command line. We want to diagnose "what's really going on" without possible UI or other glitches in the way.
