[strongSwan] what does multiple ESTABLISHED staet for a connection mean

I do have start on both the peers as I need to connect on start of the ipsec on both sides. Is there an alternative approach ?

Also I think uniqueids are enabled by default, I have not turned them off.

This means that you have two IKE_SAs established between your peers.
Might happen if both configurations use auto=start, or auto=route triggers tunnels simultaneously. Have a look for the "uniqueids" option in the ipsec.conf manpage to avoid multiple tunnels between the same identities.
