You can always bring up an HE IPv6 tunnel and hand out public IPs that way.

Hi,

We are running a small-ish LAN event in Toronto where we have to use a
single IP address to NAT between 250-350 players. I have been made aware of
possible issues with different services like Steam, Origin and Twitch who
can run into issues when a large number of connections seem to originate
from a single IP address. I just wanted to poke the list to see if anyone
can chime him on their experiences with NATing customers and the impact it
might have on public services. I am usually using public IP address space
for players when designing most large LAN events. Dealing with NAT for a
medium-ish amount of customers is not something I am used to do.

It feels silly to worry about that when you assume that WISP
sometimes(mostly?) use CGN when providing internet to customers. The same
could be said of most large office buildings around the world.

I appreciate any input on the matter!

Thanks

Laurent
