Hi,

¿Is there any info in the logs? Have you applied a SP recently?
I´ve had problems with securemote where the key exchange failed due to a bad cp.macro file. Take a look at cp.macro file in order to
see if there are or not references related to IKE (below MACRO fw1:4.1:vpnmgmt      ca   )

good luck
