SNAT


SNAT is used ie. for sharing a internetconnection.

SNAT also has two variations called MASQUERADE and
SAME

MASQUERADE
this is the same as ip_masquerade in ipchains
a connections sourceaddress is replaced with the address of the interface the connection goes out via
SAME
a version of SNAT that make sure a client always get the same sourceaddress on all it's connections

So how to we setup a simple MASQUERADE with iptables?
