Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Your title does not say it all. I'm sure it's a simple language issue, but you mean except, not accept, and within iptables they mean very different things. And you've not said what distro your using or firewall management tool to know how to best achieve this.
Basically within iptables you would probably just want to add something like
iptables -A INPUT -p tcp -s a.b.c.d -dport 22 -m state -state NEW -j ACCEPT
Assuming that the rest of your firewall handles established connections generically and such.
