With this package it is possible to make SNAT with IPv4 on the router
The user must set a peer_ip setting in gateway.meta.peer_ip 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 peer_ip 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
