Why can't they use those apps through NAT? I do it from home quite often.
Are you going to set up the port forwarding for 500,000 customers? 1 million?
You and I can set things up so port 22 goes to one machine, port 23 to another, etc., but what are you going to do for 500,000 customers?
Based on Cisco: http://www.cisco.com/warp/customer/701/60.html "As a result, Cisco IOS PAT [Port Address Translation - HN] supports about 4000 local addresses that can be mapped to the same global address." -Hank
And what are you going to do for only 1,000 customers, with some of them wanting telnet, some VNC, some ssh, some Napster, some webcams, etc. etc. etc.?
Set up a dozen ports for each of 500,000 customers?
Or do you have some magic NAT that automatically figures out every protocol, known or unknown, currently existing or yet to be written, and routes it to the correct machine?
