SOCKS gets you end to end (though it's arguably not "real"!) by letting you have listening sockets (which NAT doesn't). There is indeed a scaling issue with NAT/SOCKS as both need connection state on the gateway device - but, I suspect, the dropping cost of hardware versus the rising cost of IPv4s will favour more hardware. The real question is how it'll stack up against the cost of dropping IPv4 for IPv6 (not the cost of adding IPv6 support alongside IPv4, which isn't that hard). |
