I am reconfiguring my Windows Firewall with Advanced Security rules to protect my pc from it's own network - working on seperating my pc from my landlord's network, but that will have to wait. The Firewall Questions for beginners and Windows Firewall with Advanced Security: Guide for Vista stickies here are wonderful sources of info but I could a little help with a couple of rules. I am leaving the most of the default public profile rules for the moment until I can get the private profile tightly secured and working properly. I am going for a block all outbound not specifically allowed policy here. 1. Browser Issues: I have internet connection but can't browse the internet. Current Outbound Rule for %ProgramFiles% (x86)\Mozilla Firefox\firefox.exe Local Address: Any / TCP 1024-5000 - Remote Address: Any / TCP 80, 443 AND (for DNS) Local Address: Any / any port - Remote Address: 192.168.0.107 / UDP 53 2. From The Firewall Questions for Beginners thread: Netstat on my landlord's pc shows the above info. I have blocked in/out udp 1900 (as well as TCP 135-139, 445). I'm getting 5-20 of these per second: - (local port and size vary) DROP UDP 192.168.0.1 188.8.131.52 1454 1900 366 - - - - - - - RECEIVE Is there anything else I should do about this? And can anyone tell me what is wrong with my fw rules?
