[LARTC] masq vs snat

[Alexander Trotsai]

Hi all

Is snat /x -> 1IP equal to masquerade? If I want specify
address for masquerade, could I use snat for this?

As far as I know (and from what iptables manpage says) MASQ is similar
to SNAT with just a single source IP address to choose from, with the
addition that all connections MASQed through this interface are
lost (forgotten to be precise) when the interface goes down. This should
happen when you redial your ISP and get a new IP or when DHCP leases you
a different IP address. In any case, your IP changes and there is no
point keeping state for connections that will never succeed any more.

My firts post to the list, hopefully not the last :-)
