If I have a router with a built in firewall and I set up a web server for development work on my lan behind the firewall will I be able to access the web server sites but the outside world will not?

If you go the "firewall appliance" route, such as SinocWall, you're looking at close to a thousand bucks (the last time I checked). If you go the "I'm taking a PC, putting multiple network cards in it and making a firewall out of it." you can get away for free if you have the hardware readily available. My firewall is a P3-700 PC with 256MB of RAM, an 8GB hard drive and 4 network cards. Hardware-wise this firewall is way overkill for what I need, . I wouldn't recommend anything less than a P2-333 for a firewall though if you have a DSL or cablemodem based Internet connection. For an OS it's running a hardened minimilistic flavor of Red Hat Linux 8.0. I'm running the built-in IPTables firewall for all of my firewalling needs. That makes the OS and firewall free too. --- Jim DeMarco <Jdemarco at hshhp.org> wrote: > Thanks Martin. > > >From what I'm gathering from this thread I should > look into a hardware solution (that the fact that > I'm running WinME on a P200 that's a relatively slow > performer as is).
