RE: iSCSI: IPsec tunnel / transport mode decision

["Ofer Biran" <BIRAN@il.ibm.com>]

Saqib,

Mandatory transport mode would make bundling of external IPSec
impossible, while tunnel mode is not more difficult to implement
within the iSCSI endpoint than transport mode.

"Cost of ownership and complexity of deploying a stand-alone
IPsec gateway" might be among the considerations of vendors and
customers, but I don't think the standard should block such
solutions (and  it blocks more than just stand-alone IPsec
gateway).

  Regards,
   Ofer

Subject:  RE: iSCSI: IPsec tunnel / transport mode decision



What about the cost of ownership and complexity of deploying
a stand-alone IPsec gateway for use with IPsec end-points?
If transport-mode IPsec is a must-to-implement capability in
iSCSI end-points there is an opportunity to have much
more coherent security for iSCSI.
