ssh through firewall

Hi everyone, we are using SuSE 6.3 and want to configure our firewall using ipchains. a) How can we let ssh passing through, while ssh is using port 22 plus some "changing ports" i.e. some time port 1020, another time port 1023 and so on. b) How has the firewall to be configured when we want to use TeraTerm-ssh, which uses ports 22 and ports somewhere around 63500? I couldnt find anything about it neither in ssh-docs, nor in ipchains-docs.
