What firewall for LAN with ipcop like interface ?

Hi, I have ipcop (www.ipcop.org) acting as firewall/nat router in my home LAN. I like its easy interface and setup. But would like to add some other things to my EPIA PC running ipcop (video surveillance, VOIP) - and I thought using more general distro would be easier way. I'm Suse fan so I'm curious what app would let me do similar Firewall/NAT router system with easy web interface or other interface under Suse ? Thanks in advance, regards, Rob.
