[Swan] Multiple clients behind same NAT network

The second client from the same nat network could not connect to the server, I will check all the logs again tomorrow.
First I want to configure everything via ipsec+xauth but ipsec+l2tp I will also use.

I thought that was no longer neccessary? Recent versions should handle
multiple clients behind the same NAT. Since every instance gets its own
IP address, there is no need for overlapip= since you are not using
transport mode. the overlapip= option was in use for L2TP/IPsec in
transport mode where clashing clients use the same pre-NAT IP adress
from behind different NAT routers.
