Windows 2008 R2 Standart Sunucu (64bit) üzerine kurulu bir VirtualBox var. VirtualBox içinde bir CentOS 6.3 çalıştırıyorum. Sabit bir IP adresi ile Bridged Networking'i kurdum. İşler iyi gidiyor, müşteriye ve müşteriden dışarıya ping atabiliyorum. Ayrıca VM'ye SSH de verebilirim.
Ancak, istemcide çalışan diğer hizmetlere erişemiyorum.
İşte garip şeyler, ping:
> ping -c 2 192.168.218.23
PING 192.168.218.23 (192.168.218.23) 56(84) bytes of data.

ve nmap:

Note: Host seems down. If it is really up, but blocking our ping probes, try -PN

ve nmap -PN:

Ancak, burada VM istemcisinin ağ adresi:

Öyleyse neden 8983 veya 111 numaralı limana dışarıdan erişemiyorum?
