The SPA-2100 will perform NAT between the LAN and WAN ports. It means
that you won't be able to connect to devices "behind" SPA-2100 from
the WAN side (except by configuring DMZ, but it's gets awful then).

It also means that you can't chain them with their basic config,
because it won't like having the same network address (192.168.1.x) on
both its interfaces.

So right now, if you want to chain them, you have to play with IP
addresses, DHCP settings, etc. Not fun, particularly when you consider
that this device is really "plug and play", it remotes configure
everything.

Hopefully a "bridge" mode will appear in a later firmware upgrade
(which, for Sipuras, are frequent and readily available on their
website).
