Hi, I'm using the generic system-config-securitylevel-tui program on a remote server to configure my firewall. So far it's been fairly decent, allowing me to open up ports and whatnot. But I want to start blocking a couple of outgoing ports on my machine. I want to lock it down so the only traffic going in our out of my machine is stuff that I specify. Is there a way to do this

Hello I have set up NAT with iptables for an openvpn connection, so that the VPN server could give VPN clients access to the entire sub-net of the server. The probelm is if I start system-config-securitylevel to say disable the firewall, and then again to enable it, my iptable rules are gone ! I did run `service iptables save` before. Is there something I can do to prevent this ? Is there a

Hi, I'm using the preconfigured firewall that comes with CentOS 5. I configure it with system-config-securitylevel-tui, close all ports except SSH, and then open only the ones I need.

I go into that tool either via command line or via the GUI and I simply click "ok" and samba is suddenly open. Does anyone know what

Greetings: i have a pretty stock CentOS 5 machine with ports 80 and 22 exposed, so my /etc/sysconfig/iptables file is pretty standard/straightforward. my question is: how is this config file initially generated? i'd like to re-create it, and add a couple of rules .... so i don't want to lose what's in there already. i see that my /etc/sysconfig/system-config-securitylevel has
