I thought you were talking about devices that are immediately downstream of a particular router, not potentially many hops away. E.g. a router with thousands of devices on its LAN interface. > For a non-NAT-router, bandwidth and routing tables are the only issues. > For a NAT-router, you need far more memory because it also has to take > care of connection states and NAT tables... I think you brought this up in the context of IP to cellphones. I think the routers will need to keep track of considerable wireless state to implement this, and that may limit the number of cellphones that a particular router can handle. -- Barry Margolin, barmar@alum.mit.edu Woburn, MA
