Saqib -----Original Message----- From: owner-ips@ece.cmu.edu [mailto:owner-ips@ece.cmu.edu]On Behalf Of Ofer Biran Sent: Thursday, November 01, 2001 4:31 AM To: ips@ece.cmu.edu Subject: iSCSI: IPsec tunnel / transport mode decision I'd like to drive this open issue into group consensus. It seems to me that the tendency was more toward making tunnel mode a MUST as iFCP and FCIP did, mainly due the option of integrating an existing IPsec chip/box with the iSCSI implementation offering. If we reach this decision, we may choose even not to mention transport mode (as MAY or some other recommending text). There is an excellent analysis made by Bernard Aboba in Section "5.1. Transport mode versus tunnel mode" of draft-ietf-ips-security-04 ( http://www.ietf.org/internet-drafts/draft-ietf-ips-security-04.txt ) that can help us with this decision (also Section "5.2. NAT traversal" is relevant). Regards, Ofer Ofer Biran Storage and Systems Technology IBM Research Lab in Haifa biran@il.ibm.com 972-4-8296253
