Question regarding iptables


This question may seem dumb. Sorry...

If i'm running my box behind a rounter that's running Tomato firmware, is there a point to keeping iptables enabled?

I mean, if i'm doing all my forwarding and such in my router i wouldn't think i would need iptables.

Once again, sorry if this question seems dumb.

Thank you in advance for your help.

I guess it depends on the reliability and configurability of the external firewall.

And also in the degree of reliability of your local network, and whether there are other vulnerable machines on your local network or not (read: machines with windows installed ). If there's a vulnerable machine and it gets infected, then your whole local network with be exposed to the threat. In that case, having per-machine specific firewalling and AV can help.

Treat host-based firewall as the last-line of defense.. for the host.
