Hiya, Can someone help me with ICS? I have 2 PCs. My P4 is connected to an NTL set top box via a USB adaptor. This appears as a network adaptor and works fine. The motherboard has a LAN connector. My P3 has a LAN card installed and I connected the 2 LAN connections with a crossover cable. I enabled TCP/IP and NetBEUI and shared the internet connection. Works fine unless I try to use a Firewall (and I want one, keep getting people trying to make connections to me I don't want). I'm using Kerio personal firewall and I tried making a rule allowing any protocol, in any direction from the IP address of my P3, no joy. It's also in "Ask if traffic doesn't match a rule" mode, doesn't ask anything. Any idea what I'm missing? Thanks, d
