• If you specify the "Authentication and High Level Encryption" security level in encryption key auto
exchange settings, also select the "Master key perfect forward secrecy (PFS)" check box in the Security
Filter Properties screen (which appears in step 29). If using PFS in Windows XP, the PFS group number
used in phase 2 is automatically negotiated in phase 1 from the Diffie-Hellman group number (set in
step 11). Consequently, if you change the security level specified automatic settings on the machine
and "User Setting" appears, you must set the same the group number for "Phase 1 Diffie-Hellman
Group" and "Phase 2 PFS" on the machine to establish IPsec transmission.
