Does IPv6 use UPnP?
More specifically the technique – dubbed IPv6 unmasking via UPnP – relies on UPnP NOTIFY packets to uncover pairs of IPv4 and IPv6 addresses on dual-homed hosts configured to support both protocols. Then, we perform full port scans of uncovered pairs and compare the open port states on the IPv4 and IPv6 side.”
Do you need IPv6 for port forwarding?
If the devices want to host servers, then they have to punch a hole through the device hosting an Internet connection using port forwarding, UPNP, or related technologies. IPv6 does away with the need for NAT, port forwarding, and the lot and allows every device to have its own public IP and associated ports.
Can you use NAT with IPv6?
Myth: The lack of NAT in IPv6 reduces security Because NAT exists to overcome a shortage of IPv4 addresses, and because IPv6 has no such shortage, IPv6 networks do not require NAT. A side effect of this is that the internal addresses of the hosts behind the NAT device are obfuscated.
Who owns IPv6 address?
The US Department of Defense has 42 million billion billion billion IPv6 addresses. Just as it did with IPv4, the US Department of Defense has managed to get its hands on a huge chunk of the addresses of its successor, IPv6. The US DoD has a /13 IPv6 block (the smaller the number, the larger the block).
How does the port forwarding feature interact with UPnP?
On the USG models, it is necessary to manually configure a Destination NAT (DNAT) + WAN firewall rule to forward ports on the WAN2 interface, see the section below. How does the Port Forwarding feature interact with UPnP?
Do you have to use NAT with IPv6?
With IPv6 you cannot rely on NAT, and thus, yes, you have to configure reasonable packet filtering rules on the router or firewall. For stateful filters this is easy to accomplish: Allow all outgoing traffic and allow all incoming traffic that is related to the outgoing traffic, drop anything else.
What happens when my ISP switches me to IPv6?
When my ISP switches me to IPv6 are those accessible from the internet/do I need to create firewall rules on my home router (similar to port forwarding)/will there be something like UPnP for programms like bittorrent? Are there other security considerations?
Is there a difference between Nat and firewalling?
NAT and firewalling are completely orthogonal concepts that have nothing to do with each other. Because some NAT implementations accidentally provide some firewalling, there is a persistent myth that NAT provides security. It provides no security whatsoever. None.
