I'm cool cuz I Fold
Proponho um teste para apurar a eficácia das vossas firewalls:

https://www.grc.com/x/ne.dll?bh0bkyd2

Depois de carregarem em proceed, vai aparecer uma página e em baixo estão diversos testes que podem fazer.

O site analisa se o vosso PC é seguro no que respeita a intrusões. Avalia a resposta a pings, estado das portas (abertas, fechadas ou em Stealth Mode), etc....

Era fixe que postassem screenshots e dissessem quais as vossas firewalls para apurar a eficácia...

Deixo já o meu screenshot do teste de portas:



Firewall em questão: BitDefender Total Security 2009

Solicited TCP Packets: PASSED — No TCP packets were received from your system as a direct result of our attempts to elicit some response from any of the ports listed below — they are all either fully stealthed or blocked by your ISP. However . . .

Unsolicited Packets: PASSED — No Internet packets of any sort were received from your system as a side-effect of our attempts to elicit some response from any of the ports listed above. Some questionable personal security systems expose their users by attempting to "counter-probe the prober", thus revealing themselves. But your system remained wisely silent. (Except for the fact that not all of its ports are completely stealthed as shown below.)

Ping Reply: RECEIVED (FAILED) — Your system REPLIED to our Ping (ICMP Echo) requests, making it visible on the Internet. Most personal firewalls can be configured to block, drop, and ignore such ping requests in order to better hide systems from hackers. This is highly recommended since "Ping" is among the oldest and most common methods used to locate systems prior to further exploitation.

Isso é muito facil de resolver basta nao permitir o envio de ICMP Echos na firewall.

Quanto a minha firewall, tenho 3 portas abertas, e o resto tudo stealth. 3 Portas que estão abertas precisamente porque estao a correr serviços.

Firewall é do router, Draytek 2910.

A firewall do meu router não tem lá muitas opções, até a tenho desactivada..., prefiro ficar com a firewall por software (o tal bitdefender)...

[EDIT] Lool, eskeçam, tive agora a verficar e de facto é o router que está a bloquear as conexões, não chega sequer ao BitDefender...
