Suse firewall and asterisk


Hi, I quite new to linux suse 9. I wanted to implement some firewall setting on my sip server. The problem is that i don't know we to start. I'm thinking that if I implement such thing would block the connection(sip) to my other server/partners in other country. I have a boogey last time. How can I implement the firewall without affecting the asterisk,sip connection to other servers. How can I also allow a sshd connection to certain IP address.Here is what I've got the on the logs.
