The story so far: Until recently, I had a single PC connected to the web. OS is Win XP Pro SP2; connection type is ADSL; and, I've been using Sygate Personal Pro 5.5 (yes, very old -- but working for me).
Lately, I got two more PC's I wanted to hook up. So, I got a wireless router (AirLive WT-2000R, which was actually supplied and installed by my ISP). This router seems to be conflicting with the firewall. I will note at this point that the PC in question is wired to the router, so the wireless part may be meaningless.
The problem is that I am unable to surf the web when the firewall is on. If I set the firewall to "allow all" traffic, I can surf without problem, even with the windows FW on. But if I set it to "normal", surfing is blocked. I do not get a popup asking for permission -- only timeouts.
I googled for this problem, and it seems wireless router - firewall (and Sygate specifically) conflicts are not uncommon. However, I have not managed to find a solution.
I should also mention that I am able to ping sites even with the firewall on. But actual surfing is blocked. When I check the traffic log, I see a couple of blocked packets from the router's IP, but most packets do come through.
Things I tried, but didn't help:
1. I added an "advanced rule" to allow all traffic from the relevant IP range, and even from all addresses, for all interface cards, all applications.
2. Uninstalled + reinstalled sygate several times, making sure I had clean uninstall.
3. Cursing a lot.
Any words of wisdom?
