With this package it is possible to make SNAT with IPv4 on the router
The user must set a routerip setting in gateway.meta.routerip to get a single ip for peering interfaces.
At ipaddr the user must set a ip that not use in babel (e.g. 192.168.0.1/16) for the clients
With this package the ipaddr address is SNAT to the routerip and every router need only one
freifunk ip and can use the same ipaddr on every router.
It is a system like cgnat from big provider
