FOR ipsec, does manual Key is the key-exchange-way other than IKE or the special mode of IKE

[frederick van tagero]

I want to build a simplest IPsec use freeswan, and notice the option of keyexchage=ike is default and the oonly option. however, I remember there are much case only need preshare manual key.

so I doubt whether manual Key is the key-exchange-way other than IKE or the special mode of IKE.

or in other simply word, can IPsec/freeswan can work without IKE?

best regards,

IKE is Internet Key Exchange protocol, used by IPSec, among other protocols, for the key exchange moment. Using IPSec means using IKE protocol, whereas you set it up to do it manually or automatically is another thing.

Does it reply to your questions ?
