Thanks for playing Netmasks Of Doom this evening! Sadly, both eth1 and eth2
are in the same network - notice how the netmasks put 172.24 in the
"network" part of the IP address while all the rest is in the host part?

The CORRECT answer is: Try using 172.26.42.200 for the DMZ - that will fix
this particular problem. You will also need to re-address the inside of your
router. Note that the "correct" netmask for the 172 private range is
255.240.0.0 (172.16.0.0/12 - from 172.16 through to 172.31 as the network
stub).

But don't worry, contestant - you still go home this evening with a nose
fork plated in SOLID 24 carat gold, a loaf of stale bread and twenty seven
dollars and fourteen cents in CASH!! (cash...cash...cash....)
