Does VPN go through NAT?

VPN provides a means for performing network address translation, called VPN NAT. VPN NAT differs from traditional NAT in that it translates addresses before applying the IKE and IPSec protocols. Network address translation (NAT) takes your private IP addresses and translates them into public IP addresses.

How do I use NAT in VPN tunnel?

NAT for traffic in VPN tunnels

1. Set the Site element that contains the private local addresses (before translation) in the Private mode in VPNs in which those addresses are translated using NAT.

4. Always take note of the WAN IP of our VPN router regardless of whether you go DHCP or Static.

How does Nat t work?

Network Address Translation-Traversal (NAT-T) is a method for getting around IP address translation issues encountered when data protected by IPsec passes through a NAT device for address translation. NAT-T encapsulates both IKE and ESP traffic within UDP with port 4500 used as both the source and destination port.

Does VPN have a static IP?

Usually, VPN services own a small number of addresses for each of their servers. Some VPN services offer static IP addresses, by default or as an option. A shared static IP address VPN service has advantages over the standard dynamic IP service.

Do you need a static IP to use VPN?

The general consensus (which I agree with having set up many VPNs over the years) is that for reliable site to site VPN, one end must be a static IP address. For a remote access VPN (on demand, not full time, not site to site) a dynamic IP address at both ends can work well with a dynamic DNS service (e.g. noip.com).

What is site-to-site VPN Azure?

A Site-to-Site VPN gateway connection is used to connect your on-premises network to an Azure virtual network over an IPsec/IKE (IKEv1 or IKEv2) VPN tunnel. This type of connection requires a VPN device located on-premises that has an externally facing public IP address assigned to it.

Can a VPN be set up behind a NAT router?

I need to set up a site to site VPN with a Cisco 871 on one side behind a NAT router. Ports 500 and 4500 are forwarded to the 871 router. This should be a fairly standard configuration. The above diagram shows everything for clarity. If the 871 VPN router was the public router, this would be fairly straight forward with a crypto map.

Is it possible to have a site to site VPN?

So it is possible to have a site to site VPN using NAT-T even though one end is on a Dynamic NAT Cellular Connection? HQ does have a static IP, so this could be the solution I’m looking for.

Can a VPN be setup with static IPs?

We’ve been doing that since our ISP has converted dynamic IPs to NAT. As long as you have got your HQ on static, this is possible. We are using IPSEC and DynDNS service use hostname instead of IP address. At times, you will need to enable NAT-T (NAT Traversal), but there are also some sites which I do not enable it.
