Hi Krishnamohan,

I'm not an expert at reading the iked.log files, but I think you are
getting further than you were before.  The log entries below suggest to
me that you may just have the Phase2 settings not quite correct:

11/06/23 14:14:38 ii : phase1 sa established
...
11/06/23 14:14:38 ii : calling init phase2 for initial policy
...
11/06/23 14:14:38 ii : received peer NO-PROPOSAL-CHOSEN notification

Unfortunately, the iked.log does not tell us what settings the VPN
gateway is looking for. If you have access to the VPN router, check the
Phase2 settings that are defined for the VPN and tune the Shrew site
configuration to match.  If you're not the adminstrator, contact them
and ask what settings are required.

Regarding your setup, the IP ranges seem fine, none of the overlap
which is often a problem.  The  question at this point is the VPN
gateway configuration, how it is setup and what parameters it expects.
