by using iptables (netfilter), the linux kernel's packet-state filtering firewall system...

if you post your current iptables script, someone can show you what you need to change...

basically, the rule to add would look something like this (when doing DROP on INPUT by default):

iptables -A INPUT -p TCP -s 192.168.0.1 --destination-port 22 -j ACCEPT

(replace 192.168.0.1 with the address you want to allow)
