I don't think that would make sense. If an intruder could exploit the web server to gain root privileges, why would he stop from changing the iptables rules? If you don't trust your firewall, throw it away and get some other. IMO it would make more sense to move the web server into a DMZ instead. > Are there any advantaqes or disadvantages to having two firewalls set > up this way? You will have to maintain two rulesets, which will make your firewall more complex and therefore more susceptible to security breaches. IMHO.
