afaik, you can select, during installation, to allow ssh traffic
through the firewall.
to do it after installation, one would tipically run

iptables -I INPUT -p tcp -s <source_ip> --dport 22 -j ACCEPT

to allow ssh traffic from <source_ip> to the local box. you can run
this more than one time with a different ip address each time to allow
access from multiple addresses. to save this configuration so that it
persists after a reboot, you also need to do

service iptables save
