This text describes a change to the Npv7. It will be included in the final documentation, so feel free to correct it. But if you want to change the system here described, please contact us first.
If the nodes are in restricted mode (compatibility with the Internet), they should share their Internet connection. This can be easily done, in fact, if a node X, connected to the Internet, activates the masquerading, it is possible for the other nodes to connect by setting as the default gateway their rnode which lead to the node X.

Each node sharing the Internet connection has to masquerade its interfaces, so iptables must be used. In order to keep the daemon portable, NetsukukuD will launch the script found at /etc/netsukuku/masquerade.sh, which in Linux will be a simple script that executes "iptables -A POSTROUTING -t nat -j MASQUERADE".
