So for various reasons, I run two routers on my home network. One is the Rogers supplied SMC POS. I treat this basically as a modem and connect to it with my new Dlink DIR-655 gigabit router. I recently had a need to get some traffic routed to an internal machine and dreaded having to figure it all out. Looking at the SMC, I realized it had a DMZ option. Setting that to the “external” IP of my Dlink router would in effect pass all traffic to my Dlink, letting it handle all security related issues, including routing of traffic to internal IPs. Done and Done.

Is there any drawback to using a second router internally?
I have a 24 port GB switch handling the internal duties, and the router (currently something made by Thompson that Teksavvy sold me) doing the routing duties. I do have a second router (the WRT54G), but it’s offline now.
Since I’m now cap-free, I’m going to start getting stuff via torrents, so I’m going to need to get some hot MLPPP action going to avoid Bell’s bullshit. The WRT54G is a prime host for custom firmware — I should be able to just passthrough everything to it, and have it do the duties, without any issue, right?
The advantage for me is that I get to use a decent router, rather than the SMC junk Rogers provides, plus it’s gigabit, acting as my internal switch. With two routers like this, you get a double NAT going on which can cause problems, but I haven’t run into any yet. Heck, I even get my VMware OSs online without any trouble at all.
It sounds like you could do the same as I just did and put your WRT54G in the DMZ (if your router supports that) and let it handle everything from there.
