I think you would benefit from looking into the MOBIKE capabilities of Strongswan. This is there to cater with the change of IP address and re-homing the connection.

Subject: [strongSwan] regarding dns resolution

I want to know how the dns is resolved in strongswan.
if i give right=rakesh.com<http://rakesh.com> and for this a particular ip is written in /etc/hosts, so the connection goes up easily.
But in logs it shows the ip while connecting this means that somewhere inside the name is replaced by ip.
what actually happen???

also i made other side "rakesh.com<http://rakesh.com>" to drop esp packets and changed the ip address of "rakesh.com<http://rakesh.com>" in /etc/hosts while live connection.
when i ping "rakesh.bansod" it tries to recoonect to "rakesh.com<http://rakesh.com>" because of dpdaction=restart.
but problem is that it didn't knew that the ip is changed and still tries with the same ip.
also i tried ipsec update, but it didn't worked.
what should i do if i now the dns of other party which keeps on changing its ip address then how to make connection in such case.
please help.

thank you.
