Just use IKEv2 then you can have concatenated subnets.

    Hi Andreas,

    Thanks for you reply.
    Earlier we were using openswan where in the config 'keyexchange=ike'
    is set (which is ikev1 correct me if I am wrong). In openswan
    multiple subnets with comma separated worked.

    In strongswan if we setup connection for each subnet, a separate
    tunnel will be created for each connection. For connection status,
    bring up/down we need to do on each connection. Earlier in openswan
    we used to manage as single connection.

    Is there any way to manage it as single vpn connection or tunnel ?

    Thanks,
    Jayapal

        Hi Jayapal,

        The IKEv1 protocol does not support comma-separated subnets, so your
        problem is independent of the strongSwan version. You must set up a
        separate connection definition for each subnet.

        Regards

        Andreas
