Oh, this is *not* what you want to see. I recommend against the DSL router - use that more as a edge device (edge of the network), and run your own network inside of it, so that you can add another edge device in tandem, or replace it/them without disrupting your network.
I'd think about another layer 2 or better device (Gig ports) located there.
BTW - can you get cable modem service at your location? DSL is not your friend, unless you have no choice of other friends.
OK - so it sounds like I should be doing something like this:
1. Replace the consumer-grade Trendnet Gig switch with a better switch.
2. Connect the server straight to that better switch.
3. Connect something like the D-Link DIR-655 to that better switch for router and wireless functions (as an "edge" device).
Now the question is, do I connect the DSL modem (or maybe cable modem) to the Switch or the D-Link DIR-655?
