Behind router firewall, do I need iptables etc?
I am behind a router, as you can tell I am very new at this, do I still need to configure iptables for security? If so what should I do? I host a website from my centos 4.3 system.
The reason I am asking I see hits on my system to ports 2888, 37294, and 32806. what ports are those?
I guess i would need help configuring a good set of iptables or chains... not sure.
If you're in any kind of local network, the answer is yes. Router (with firewall!) helps only when only trustes machines are behind it (well...it's always better to have them all firewalled, just in case).
The router-firewall protects you (maybe) against hackers from the outside net.
If you have suspicios users in your local lan, then only a firewall on your system can protect you.
Just search for "iptables" in ths forum, there are plenty of threads.
The ports you mentioned are beyond 2048, according to my understanding, this means that your outgoing connections use these ports, it would be great if someone with more tcp-know.how could confirm this, I am not too sure about this.
How did you check: netstat -ant ??
