Hello John,
All IPV4 addresses are now assigned.
Any thoughts on how much work it would be to make D-Rats be IPv6
compatible?? IPv6 is clearly the future of the Internet, most ISPs
support it now, and the ridiculous number of IPs you get from your
ISP are all publicly reachable.
If it does not match the whatismyip.com report, then running a
public ratflector is a lost cause.
It is very likely that your configuration is:
public Internet IP -- ISP NAT private IP -- Your router -- Your
network with private IP addresses.
This is not entirely true as a user has at least two more options:
? - The ISP's operated NAT is usually a form of Carrier Grade NAT
(CG-NAT) which should be able to support port forwarding via Port
Control Protocol (PCP) - .?
The enduser will need to contact their ISP to see if they support
PCP for their endusers
? - The end user can setup a VPN with a provider that supports port
forwarding or supports static IPs for their tunnels.? I've heard
good success with vendors like vultr, etc.? The VPNs aren't too
expensive to operate.
Also it is recommended that UPNP (Universal Plug and Play) be
disabled.
I also generally recommend disabling UPnP as most of the router
implementations of that stack are known to have many various
security vulnerabilities (Google it.. it's really bad).?
Unfortunately, some of the CG-NAT solutions out there support the
configuration of PCP via the enduser's UPnP stack.? Again.. the user
will need to contact their ISP to understand how it's done for their
specific network.
