I’ve had Sunrise Internet Box for almost two years and since yesterday evening the Sunrise DHCP servers assign to my WAN IP interface a shared IPv4 address, Carrier-Grade NAT RFC6598, eg 100.96.177.254. Now all my Internet traffic is proxied through another public IPv4 address which belongs to Sunrise.
I have called Sunrise support to complain about the fact my box is not directly reachable from Internet and I cannot connect anymore to the RoadWarrior VPN Server listening on my Sunrise Internet Box, but the level 1 support failed to see any problem with the router.
How could I have again on my Sunrise Internet Box a public valid IPv4 address, directly reachable from Internet?
Thank you.
