After reading this review, I… Continue reading Which VPN offers more security conceptually, SSL VPN or L2TP/IPSEC?
Please explain purpose of the following commands and differences between them.

We’re setting up some new tunnels and have been told to use IKEv2. I understand that IKEv2 allows different authentication methods, e.g. one side using PSK and the other using a certificate. We don’t have a PKI so it’ll have to be PSK for … Continue reading IKEv2 Using Different PSKs
I am trying to set up VPN on my iPad, but I am given three unfamiliar choices: IKEv2, IPsec, or L2TP. The only thing I know is rumors that IPsec has been targeted by the NSA, but that’s not even helpful in making an informed … Continue reading IKEv2, IPsec, L2TP for iPad?

What happens if a laptop and a server don’t have a encryption algorithm in common?
Does IPSec abort the connection or does it always have default algorithms?
So if we have a server configuration with local auth pubkeys and remove psk and at the same time for a client(initiator) a local auth psk and remote pubkey.
Something like this.
Server –
local {
round = 1
id = 10.3.72.136

Firewalls implement IPsec VPN and perform packet filtering. IP Encryptor, on the other hand implements IPsec VPN and achieve security goals (confidentiality, integrity and authentication).
What are the advantages of IP Encryp… Continue reading IP Encryptor and Firewall
