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. Stephen PS We're assuming IPV6 will not be required. ==================== Stephen M.
