Umm...any redundant PC with two network cards and ZeroShell, hooked up on one card to a switch and the internal network, and with the other card to the modem...
Or, the same PC with any distro.
Good luck

I think your question is regarding being able to install linux on a low-power device moreso than a "regular" computer. If that's the case, there are a number of routers available on the market that can be re-flashed with aftermarket firmware such as dd-wrt or OpenWRT. Both of these work pretty well--it's mainly a matter of verifying which devices are compatible with your chosen firmware.
Although there are some combo modem+router units in use by various DSL companies and utilities, it's probably less likely they can reprogrammed in the same way many of the router-only hardware devices. In any case, be prepared to keep the modem and then either try flashing a Linksys WRT54GL (or similar) with dd-wrt or OpenWRT or simply use an old desktop computer with two network cards as Thor suggested.
If you're new to linux I'd probably start by practicing with an old desktop--they're a lot easier to reload if you make a mistake in the configuration!
I agree with the dd-wrt deal and openwrt if that is what you are looking for along with the old pc or micro pc install. Even floppy based router firewalls exist.
You can run a virtual machine on your system that does the same thing. Distro's like untangle would be a good choice to run within your OS on a VM. Then just point your traffic to the VM and let the VM do it's thing.
