Security level Configuration

[charales]

Hi ya all!!!

I have a question about security. ¿Is it enough to configure the "Security Level Configuration" in RedHat 9 to rest peacefully?. I want to run an HTTP, FTP and Mail servers for a couple of frends and myself (no big deal).
Right now it's like this:
Security Level: MEDIUM
CUSTOMIZED to allow incoming through WWW, FTP, SSH, DHCP and MAIL.
But eth0 is not a trusted device.

My internet connection is an ADSL with a 3Com 812 Officeconnect.

Thanks in advance

I am not sure how reliable the buit-in firewall is compared to a hardware solution.
You opened the correct ports for the services you need. Enabling eth0 as a trusted device would allow all access to your pc from that NIC. So don't to this if it is connected to the internet.

Have a look at the RH customization guide

I always using firewall=none when i install a system. When i got my applications to work properly i begin to tighten up the system. That have worked well for me.
