Ethernet traffic is encapsulated in UDP packets. Each virtual Ethernet adapter

is automatically assigned a UDP port from a range that begins at the specified

base virtual Ethernet port number and ends at the base virtual Ethernet port

number plus the number of configured virtual Ethernet adapters. Each virtual

Ethernet adapter is also has a UDP port assigned at the Windows server.
|

|
|
UDP ports for virtual Ethernet are normally automatically allocated by Windows.
|
||
|
|
If you want to override automatic allocation, you can manually allocate
|

a UDP port by performing the following steps at the Windows console.</div>

<p>If IPSec is used, there are additional considerations for firewalls between

an iSCSI HBA and the iSCSI network: </p>

<li> Only IP addresses should be considered when configuring firewalls. TCP

on this information.</li></ul><img src="deltaend.gif" alt="End of change" /><img src="deltaend.gif" alt="End of change" />
