I have a small lan that is connected to the internet thru a Netgear RO318
router. On the lan, my RedHat Linux 7.1 box acts as a samba fileserver,
hosts our website, and acts as a private ftp server for me alone to connect
to from home (my home ip is fairly stationary). I've set the router to
forward port 80 and port 21 requests from the Net to the linux box. I keep
the box up to date with all the latest patches using RedHat's excellent
"up2date" service. Everything works just fine, and I *think* I'm fairly
secure behind the router (Netgear calls it a "security" router, after all).
I would feel much better though, with ipchains security tightened up just in
case the router has some sort of brain fart. I'm still a newbie, and quite
frankly, I'm just burnt out from reading all the documentation. Can someone
just tell me what I need to do?
