Hey, Myky again here,
Another question. IPSec keepalive, what is the source IP address of the packets?:

My RUT240 local subnet is 192.168.14.0/24 >> remote VPN subnet is 192.168.1.0/24
When l am trying to ping my remote subnet from RUT, it fails, however, if l initiate ping from 192.168.14.1 (router IP address) ping succeeds:

How keepalive is performed by RUT and what is the source IP address of the keepalive packet?
