Help setting up a firewall
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?
