Ipsec tunnel VPN

[shaikh.zaid22]

Is it possible to create ipsec vpn with one phase 1 parameters defined, whereas the phase 2 parameters kept non or default at both ends?

Does the tunnel will be created ? if the tunnel is created then the data traversing will be plaintext ?

I dont have a license for vpn and was just curious to know if it is possible.

@shaikh.zaid22 You need to define Phase 2 parameters, most devices have defaults - these do differ between versions. These Phase 2 parameters must be the same as used with the peer device, if they don't match then a tunnel will not be formed.

What hardware device are you referring to? If it's a router, then you can use a GRE tunnel, which would not require IPSec and data transferred unencrypted.

As long as both the side parameter matches, the tunnel will be enabled.

how secure is this config is - other question related to business ?

why IPSec if you need plaintext 
use VTI or GRE.

Actually i dont have the license the IPsec VPN and was wondering if it can be acvieved.

Yes via GRE tunnel we can achieve on router.

Then you have only option of GRE if you do not have advanced License.

Then do some ACL also helps.
