NMAP Issue with Ping

Dear All, I have a strange issue when using Nmap. I have a personal firewall. When it is enabled, I always get that the target of the scanning as down (although I am sure that the target is up since I did normal ping from my CMD and it was replying!) and I have to use the -PN switch. I thought my firewall was blocking the received packets of the TCP ping, but when I tried to do a Ping scan (using the -sP swicth, in order to do ICMP ping), I got the same issue. If I disable my firewall, everything is OK. I revised my firewall rules, but I could not find anything blocking the reply from either the TCP ping and the Ping scans of Nmap. It is very strange....this means that the firewall blocks only the ping replies (whether TCP or ICMP) related to Nmap, and allows the normal ping. This is the only conclusion I reached, but why is that? I appreciate your help in advance.
