Can any NIS Pro 2004 users please explain how to configure firewall rules for spyblocker so that it stealths port 80 instead of keeping it open. After trying many, many things and spending weeks on this problem, I've been advised by many people on various forums including spyblocker forum, pc answers internet security forum, broadband reports security forum. But nothing works. Many people say to get rid of NIS it's an overcomplicated resource hog and to install Sygate firewall/AVG AV combo which is much better. I like NIS though, if only it worked properly. I suspect that NIS Pro 2004 firewall doesn't like Spyblocker. But before giving up for good, I've been advised to ask on Wilders. So in the hope someone here can help me, here goes... Program Versions: (NIS) Norton Internet Security 18.104.22.168 - (SB) Spyblocker 7.63 Problem: Port 80 is not stealthed when SB is running (which is obviously all the time). This problem was brought to my attention after many alerts were popping up saying that someone was trying to access the spyblocker.exe program on my system. Maybe I'm being paranoid, but it seems like port 80 were increasing in frequency posisbly due to someone noticing that my port 80 was responding to port scans? Port scans from various sites, including GRC confirm that all ports are stealthed except for port 80 which is OPEN! Tests revealed that if SB was shut down, port 80 became stealthed, but obviously I want to keep it running as it catches lots of stuff norton misses. SB's author explained because SB sits on port 80 filtering everything passing through it, it acts as a web server and keeps port 80 open. But it only filters spyware, etc, I've discovered other things get straight through the firewall open port 80 direct to the spyblocker.exe program, which is not too good. NIS only stealths blocked ports, therefore it won't stealth port 80 as it isn't blocked - it's in use by SB. This is where Sygate wins over NIS, it apparently stealths all ports whether in use or not. I've tried creating program rules for SB to block incoming traffic on port 80, block outbound traffic, even blocking both ways. I've tried creating general rules for port 80 as well, but nothing works. I do manage to get port 80 stealthed by blocking inbound connections to spyblocker.exe, but this causes problems with spyblocker not working properly. The only solution I've found so far is to use the Windows XP built in firewall (ICF) in addition to NIS. This then stealths port 80. I thought if the simple ICF could stealth port 80 then surely NIS could, but apparaently not. It seems I am asking too much of it. I know I can show stealth with both firewalls running, but I see people saying not to run 2 firewalls together as it causes problems, but what else can I do if NIS won't play ball? Any help, advice, information, solutions, would be *really* appreciated.
