 Hi Stephen,

I forward this request to the more technical people who I hope can
answer  your questions.

Best regards,

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.
