OpenVPN is an SSL VPN and as such is not compatible with IPSec, L2TP, or PPTP. The IPSec protocol is designed to be implemented as a modification to the IP stack in kernel space, and therefore each operating system requires its own independent implementation of IPSec.

Dec 29, 2012 · L2TP is considered to be a more secure option than PPTP, as the IPSec protocol which holds more secure encryption algorithms, is utilized in conjunction with it. It also requires a pre-shared certificate or key. L2TP’s strongest level of encryption makes use of 168 bit keys, 3 DES encryption algorithm and requires two levels of authentication. Apr 15, 2019 · SSL VPNs work by accessing specific applications whereas IPsec users are treated as full members of the network. It’s therefore easier to restrict user access with SSL. If one of your clients works with a freelance employee, for example, they can give that person limited access to the programs they need without letting them see sensitive or However, you can improve Mobile VPN with SSL performance if you select UDP for the data channel and AES-GCM ciphers. VPN Tunnel Capacity. When you select a type of VPN, make sure to consider the number of tunnels your device supports. The maximum number of IKEv2, L2TP, SSL, and IPSec mobile VPN tunnels depends on the Firebox model. Therefore, if the virtual private network (VPN) server is behind a NAT device, a Windows Vista-based VPN client computer or a Windows Server 2008-based VPN client computer cannot make a Layer Two Tunneling Protocol (L2TP)/IPsec connection to the VPN server. Jun 30, 2020 · Layer 2 Tunneling Protocol (L2TP) is built in to almost all modern operating systems and VPN-capable devices. It is therefore just as easy and quick to set up as PPTP. On its own, L2TP does not provide any encryption or confidentiality to traffic that passes through it, so it is usually implemented with the IPsec authentication suite (L2TP/IPsec). OpenVPN is an SSL VPN and as such is not compatible with IPSec, L2TP, or PPTP. The IPSec protocol is designed to be implemented as a modification to the IP stack in kernel space, and therefore each operating system requires its own independent implementation of IPSec.

Mobile VPN with L2TP. Mobile Virtual Private Networking (Mobile VPN) with L2TP (Layer 2 Tunneling Protocol) creates a secure connection between a remote computer and the network resources behind the Firebox. By default, Mobile VPN with L2TP uses IPSec to provide strong encryption and authentication.

So, typically both L2TP VPN and SSL VPN doesnt support this static IP usage for now because of the above technical reason. The below KB article can give you an overview of how the static IP is mapped to a MAC in case of GVC users. Best VPN Protocols: OpenVPN vs PPTP vs L2TP vs Others

Both Cisco VPN client (pure IPsec/IKEv1) and Anyconnect (SSL and IPsec/IKEv2) do support domain suffix. For l2tpoIPsec stack> IP -> (typically) ESP/UDP-4500 -> L2TP (in fact seen in "show crypto ipsec sa" to be UDP/1701) And yes, rest should be pretty standard L2TP ;] Marcin
