val debug : bool

the lowest port number used by the address translation

module Nat: sig .. end

Network Address Translation (N.A.T.) is the process of replacing on the fly non routable addresses used within a LAN by a unique routable address, so that hosts from the LAN can communicate with the outside world by sharing the only routable IP address.

A router is a device with N IP/Eth devices and a routing table with rules on interface number, Ip addresses, proto, ports.

val make_gw : ?nb_max_cnxs:int -> Ip.Addr.t -> Ip.Cidr.t -> Tools.trx

A gateway is a device with 2 Eth interfaces, with a public IP address and a private network address, performing routing between these two, NAT and DHCP for the LAN. The returned TRX is seen from the LAN (ie, tx for going out)
