...jakiś czas zrobiłem sobie IPSec w trybie tunelowym między moim laptopem i AP. Wszystko w tym celu, by zabezpieczyć się przed ewentualnym podsłuchem ruchu WiFi. Niestety, jest jeden, mały problem: You can configure Windows XP as the endpoint of a tunnel mode IPSec connection. However, we do not recommend this. If you use the IPSec connection in tunnel mode, the Windows XP SP2 Windows Firewall feature does not filter any packets that come out of the IPSec tunnel. However, packets that come from other directions are filtered by the Windows Firewall feature.
