I was wondering whether kind soul could point me in the right direction. I am running Win2k with ZoneAlarm 4.5 free firewall behind a linux IPcop box. ZoneAlarm is only used for its outbound protection and I have been happy with this setup until now. However I am playing around with VNC and ZoneAlarm is blocking incoming connections on port 5500 (which I have forwarded from Ipcop to my computers internal IP). I can’t find a way of allowing traffic from a single port through ZoneAlarm only traffic from a particular IP/Range. Connections will be coming from different IPs as the other end is dialup. Looks like I need new firewall software preferably free that will allow me to open ports. Low resources and stability are my main priorities. Anyone have any recommendations?
