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 with the system-config-securitylevel program? If

Not that I am aware of.

not, what do you recommend I use to configure the firewall?

There are a couple of other programs available. I prefer firewall builder. Others will suggest programs like shorewall, firestarter, gShield, etc..
