Hi,
Last night i upgrade openbsd from 6.0 to 6.1, and Ipv6 doesn't work anymore
I will give below some useful information about my provider and some
screenshots from openbsd configurations, including output from dmesg

Name: RCS - RDS
Ipv6 mechanism used: TEREDO
Same configurations works exactly if i revert back to openbsd6.0
The problem is not that i used both ipv4 or ipv6.
