|All 4 LAN ports on your SOHO Router can be used as uplink ports. If you wanted to, you could connect 4 switches, one each to the LAN ports, and it would work just fine.|

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
