Summary of changes :
- Added a new flag -s to ipassoc command to carry if the ip address is
used for SNAT or not.
- SNAT is completly decoupled from the first flag. first flag is used
to decide if the ip address is first ip address of the interface.
- -s and -f are independent, SNAT can be enabled on the non-first ip
also.
