...or upnp and pcp, which work out of the box.
- milankragujevic 6y agoUPnP is completely useless for CGNAT, and PCP would work only IF the CGNAT gateway would support it, which most don't (or it's disabled). I don't think great difficulty about NAT is concerning CPE NAT, i.e. your local network, as it's trivial to forward ports (or port ranges) manually. Most problems are with CGNAT, i.e. on mobile broadband or some cable and DSL providers.
- bzb5 6y agoWhere I am there are more isps that support pcp than isps that support ipv6 at all (zero)
- milankragujevic 6y agoWhere I am the number of ISPs that support PCP is the same as the number of ISPs that support IPv6 - zero. My point wasn't that IPv6 is currently the answer, my point was that it's impossible to host anything or be reachable by anyone for A LOT of people in the world.
- xxpor 6y agoUsing CGNAT while not offering IPv6 at all is professional malpractice.
- cassianoleal 6y agoGood luck if you're behind CGNAT on IPv4, which an increasingly high number of people are.
- bzb5 6y agoWhich is why I said pcp. It helps to read the comment.
- cassianoleal 6y agoWhich only works if the ISP gateway has support for it and has it enabled, which in my particular case (and I suspect many others) is not true. IPv6, OTOH, pretty much works out of the box. It helps to become better informed.
