Hi Stephen, I can link you with my networking guys that did both the EGEE-3 conference and the GGF16 in Athens. For those we got 4 class C addresses (a bit more than a thousand IPs). Indeed it takes some negotiation with the national registry, but it is a standard procedure. Your hybrid solution is also ok (and maybe more secure) but indeed adds to the complexity. Let's take the rest off line, All the best, Fotis Stephen M Pickles wrote:
All,
A question has arisen regarding the network provision at OGF20 and EGEE-UF 2.
Is anyone likely to be running a demonstration in the exhibition that will involve incoming connections?
We need to be able to provide up to 900 or so IP addresses. If all connections will be outgoing, it should be possible to do this using Network Address Translation. If some connections will be incoming, then it is likely that real IP addresses will be needed.
An early response will be very helpful. Obtaining 900+ real IP addresses will require some negotiation and cannot be guaranteed at this stage. Adopting a hybrid solution of NAT for wireless and real IP addresses for wired ethernet to the booths is possible, but would add complexity to the network design and configuration.

PS We're assuming IPV6 will not be required.
