Hi Tobias,

My strongswan.conf file look like this on server and client both now :-

charon {
mem-pool {

Even this has not helped. Server assigned a different virtual IP to the client, when it came up after reboot.

Note that, strongswan version that I use is 4.3.6.

Also, there is nothing available on strongswan wiki wrt mem-pool.reassign_online option. Let us know, if any other documentation page exist for such options.

If you use in-memory pools (i.e. `rightsourceip=<subnet>`) you could
enable the `charon.mem-pool.reassign_online` option in strongswan.conf.
 If it is enabled existing online leases will be reassigned to clients
with the same identity.
