Turris how-to on UPC (CZ) network

Being fresh customer of UPC, I have their modem|router with native IPv6 and tunelled Ipv4.
I’d like to bridge the IPv6 and NAT the IPv4 - any experience regarding this|similar setup?

My goals are:

  • to have native IPv6 connectivity on network hosts
  • keep possibility of tracking the network traffic using PAKON
  • being able o restrict/manage the network security using turris iptables/firewall

My previous setup was Turris doing IPv4 NAT and IPv6 connectivity via vpsFree OpenVPN tunnel…
