opening ports

[stathisx]

in my home network ssh <slackhost.slack.org> works fine to the other pc(this who has slackware installed).when i try from the other pc to ssh <suse> it says connection refused(port 22 closed).
i tried nmap frontend program and i get for the pc which uses suse :

how can i have my ports open(ssh and ftp i want for my home network)
i have tried firestarter firewall,and it freezes when i connect to internet.i tried to configure irewal with yast and nothing happened.i also tried

iptables -A INPUT -s slackhost.slack.org -d 192.168.0.1 -i eth0 -p tcp --syn --dport 22 -j ACCEPT

in order to open port for (ssh services).
although nothing happened.
