[ To the music of "Lobster Sticks to Magnet!"]

You've got a router and you've got some bandwidth.
Router has a table, but don't you grep it.
Router made of iron; bandwidth made of bits!

You've got a router and you've got some bandwidth.
If a router hungry he can eat a packet.
Packet made of headers; router has /dev/null!

Don't let a router lose his state;
Or all his bandwidth will escape;
He'll crash right down and have you paged;
And then you'll work all NIGHT!

Router sticks to bandwidth! (shananana!) x4

SNAT north, DNAT south!
