Routing

內部外部網路未達到 TMG Forefront 2010(Hyper-V 環境)

  • January 5, 2011

下面是我的環境:

我有 1 台執行 Windows 2008 R2 的物理機,具有 Hyper-V 角色。這台機器有 3 個物理網卡:

  • 一個用於網際網路
  • 一個用於內部網路
  • 一種用於無線網路

所有 3 個在 Hyper-V 中都有各自的虛擬網路,我有一個額外的專用虛擬機網路用於 DMZ 網路。

在其中一台虛擬機中,我安裝了 TMG Forefront 2010 SP1,它可以使用所有 4 個網路。下面是防火牆的 IPCONFIG /ALL:

我在 Forefront 有以下網路:

External: IP addresses external to the Forefront TMG Networks
Internal: 10.50.75.0 - 10.50.75.255
Local Host:
Perimiter: 192.168.10.0 - 192.168.10.255
Wireless: 192.168.1.0 - 192.168.1.255

在網路規則中,我有:

1 => Route => Local Host => All Networks
2 => Route => Quarantined; VPN => Internal
3 => NAT => Internal; VPN => Perimiter
4 => NAT => Internal; Perimiter; Quarantined; VPN; Wireless => External

我的問題是我只能與內部和外部網路進行通信。如果從 Forefront VM ping www.google.com 或 10.50.75.21,我會毫無問題地得到回复。如果我嘗試在 Perimiter 網路或無線網路上 ping 一台機器,它不會被路由回 Forefront,它是所有網路上的預設網關。這裡作為 ping 範例:

對 192.168.10.3 的 ping 使目標主機無法訪問。以下是外圍虛擬機的 ipconfig:

PS C:\Users\Administrator.Administrator> ipconfig /all

嘗試從 DMZ 機器 ping 192.168.10.1(網關)也不起作用。當我使用日誌和報告監控來自無線網路和外圍網路的數據包時,我沒有收到任何我嘗試發送的數據包連結 PING 或 HTTP。但是我確實收到了很多 NETBIOS 廣播的欺騙消息……就像 Forefront 認為它來自不同的網路,但我不知道為什麼。請幫忙!

Tks

當一切似乎都正確時,那是因為它可能是!

我通過從 Forefront 中刪除無線和外圍網路解決了這個問題,然後關閉 VM,然後從 Forefront VM 中刪除網卡,然後啟動,關閉,重新添加卡,啟動,使用不同的子網(不知道是否這一步是必要的,但我還是這樣做了),啟動,將網路重新添加到 Forefront。

在這場馬拉松之後,它開始工作了。來自外圍和無線的流量開始被 Forefront 辨識,並且數據包開始正常流動,配置與以前相同
