Should I use IKEv2 or OpenVPN?

How do I setup my IKEv2 VPN?

IKEv2 is a great new protocol that was released by Cisco this year.

This protocol has the potential to improve the security, speed and user experience of VPNs. However, it's also a new protocol which has some learning curve and therefore is not yet supported by many popular VPN apps. This guide will show you how to configure IKEv2 VPNs in all the most popular VPN clients.

IKEv2 allows you to connect to the VPN server using the IPSec protocols. IPSec is one of the oldest and most secure protocols for VPNs, and IKEv2 uses the same algorithms as IPSec so there shouldn't be any compatibility problems.

What is IKEv2? IPSec is a set of protocols for encryption. When you are connected to a VPN server with IPSec, your internet traffic is sent through the tunnel created by the IPSec protocol. IKEv2 is the protocol used by IKEv1 and IPSec to establish the tunnel. IKEv2 is more secure than IKEv1 and has been introduced in Cisco IOS, as well as a few VPN apps.

The goal of IKEv2 is to solve some of the problems in IKEv1. The biggest problem with IKEv1 is that there is no strong authentication when a user logs in to a VPN, so it's very easy to create a fake VPN and trick people into connecting.

IKEv2 solves this problem by requiring the users to authenticate themselves when they log in to the VPN. There are several methods for doing this and these will be described in this guide.

How to use IKEv2. IKEv2 is now supported in the following VPN clients. If your VPN provider supports IKEv2, you should be able to configure it correctly.

Cisco IOS VPN client. OpenVPN. StrongVPN. How to configure IKEv2 in Cisco IOS. The steps described below are required to configure IKEv2 in Cisco IOS. We recommend that you create a separate sub-interface for the VPN and run the IKEv2 VPN on this sub-interface. This allows the VPN to receive all of the VPN traffic on the default interface, and other traffic can continue to go through the default interface.

What ports does IKEv2 use for VPN?

IKEv2 is based on UDP port 500 and UDP port 5001 for IKEv2 authentication and IKEv2 traffic.

IKEv2 also uses UDP ports 500, 5001, and 5002 to negotiate a tunnel for IPSec traffic. The IKEv2 traffic is tunneled over the IPSec tunnel.

What ports does IPSec use? IPSec uses UDP port 1701 for the hello exchange and UDP port 1723 for the key exchange and authentication. What ports does NAT-T use? NAT-T uses UDP port 1723 for the hello exchange and UDP port 1779 for the key exchange and authentication. What ports does L2TP use? L2TP uses UDP port 1723 for the hello exchange and UDP port 1779 for the key exchange and authentication. What ports does ESP use? ESP uses UDP port 1723 for the hello exchange and UDP port 1779 for the key exchange and authentication. What ports does MS-CHAP use? MS-CHAP uses UDP port 3389 for the hello exchange and UDP port 3389 for the key exchange and authentication. What ports does PPTP use? PPTP uses UDP port 500 and UDP port 5001 for the hello exchange and UDP port 5001 for the key exchange and authentication. What ports does the L2TP option use? The L2TP option uses UDP port 500 and UDP port 5001 for the hello exchange and UDP port 5001 for the key exchange and authentication. What ports does the MS-CHAP option use? The MS-CHAP option uses UDP port 3389 for the hello exchange and UDP port 3389 for the key exchange and authentication. What ports does the PPTP option use? The PPTP option uses UDP port 500 and UDP port 5001 for the hello exchange and UDP port 5001 for the key exchange and authentication.

What is the username and password for IKEv2 VPN server address?

We are using openvpn v2.

3.8 with IPsec v1.5.2 on ubuntu 16.04.

When the server gets the connection from client, it needs to identify the client. So we need to specify the username and password. However, we are not sure what username and password should we use.

In general, we can use whatever username and password we like. The default username and password is admin and admin, respectively. Could you tell us what username and password we should use? Thank you. Here is a very good explanation of what is required to create an OpenVPN server for IPSec/IKEv2: Specifically in your case, here is what you need to do to allow users to connect to your OpenVPN server to use IKEv2: Add the "auth-user-pass" directive to your configuration file (see example below). This will automatically populate the "username" and "password" directives in your client config file when a user connects.

Add the following directives to your config file (see example below). These directives are required by OpenVPN 2.8 to enable IKEv2.

Config # define name of the config file. Ifconfig-push # allow push of addresses to subnets. Dhcp-option # specify the subnet to assign to the clients. Route-gateway # route gateway traffic through VPN. Client-config-dir # where to find VPN config files. Example: # The server config file is in /etc/openvpn/server. # It has several different sections. You can uncomment as many # as you need, and change the order in which they are included. # By default, only one section will be included.

Should I use IKEv2 or OpenVPN?

I have a VPS hosting service and I wanted to set up an IPSec VPN connection between one VPS node and another.

The other nodes are running OpenVPN.

I went through RFC 5996 () to find out that using IKEv2, or using openvpn to the IP address of the private network is a good choice for the configuration. But I am still confused about which one I should use.

Can anyone give me any help? Thank you! With IPSec you want something more open than IKEv2 in terms of protocol support. This means that the VPN server only knows how to work with those protocols. The same is true for the encryption, key exchange, authentication, and much else. Using IKEv2, which is basically IPSec with a fancy wrapper layer, can make the server software do everything, but there may be protocols for which it is not designed. If the server is capable of both types, using IKEv2 would give you complete control over the VPN, but using some other type would allow you to do the same. Either way, it is not necessary to use IKEv2 if you need complete control.
