Help setting up a firewall

[dark_lord_kodd]

Hi,

I guess its time I set up a firewall! Kinda stupid for not doing it sooner....

Im runing slackware 10 (might be 10.1).

I have iptables installed, and also got iptables-control which seems to guid though setting it up.

What i really need help with is all the ports. THis is what i want to use it for:

1) A Samba server for sharing files with windows pc's
2) A FTP server (already set up and working) - port 21 at a guess
3) SSH so I can log in to it from LAN - port 22 at a guess
4) VNC so I can remote desktop from LAN

any ideas on which ports i need to open for vnc or smb?? ive tried a few but things grind to a halt when its turned on!

Also, once its set up, i issue the commannd "iptables start" and it gets things going, will i have to do this every time i log on?

Thanks

Look at IANA network port assignments for which ports you need for various services.

For automatic startup, just add your filewall script to your system startup scripts -- I'm not a Slacker, so I'm not sure which script it is, but on RedHat it's /etc/init.d/rc.d/rc.local.
