You certainly CAN do it that way. Being paranoid, I'm in favor of having one "box" that does firewall/routing duties without any other apps running, to reduce the exposed "attack surface". I used to run a Smoothwall GPL box as firewall, but like you, I wanted to do a little something about the power usage. My "solution' was a dedicated consumer router, which used probably (not measured) a tenth of the juice of the old PC that ran Smoothwall. I used dd-wrt on it instead of the original firmware. -- ---- Fred Smith -- fredex at fcshome.stoneham.ma.us ----------------------------- The Lord detests the way of the wicked but he loves those who pursue righteousness. ----------------------------- Proverbs 15:9 (niv) -----------------------------
