[Openswan Users] Saving peer certificate?

[Árpád Magosányi]

Hi!

I am trying to connect to a vpn3030, using strongswan. I do not have
either the cert of vpn3030 or its ca cert handy, so I am the one who
refuses the connection.
How could I either save the certificate sent by the gateway, or go on
withouth checking peer identity?

(Yes, I know that not checking the peer cert by other means is
insecure because there is a possibility of MIMD attack.)

Thank you.
