Which version of Suse for these task ?

Hello all, I am new to Suse and relatively new to Linux. I would like to put Linux on a x386 PC. The task of this station would be : - work as a router (sharing an internet connection) for my internal LAN, - work as a firewall for my internal LAN, - work as a print server, cvs server,... for my internal LAN. Can I do it with "Suse Linux 9.0" or do I have to buy "Suse Standard Server"? If I buy Suse Standard Server, did I have to pay every year ? Thanks, Jean
