Oct 10, 2016 · Traditionally, IPSec does not work when traversing across a device doing NAT. To circumvent this problem, NAT-T or NAT Traversal was developed. NAT-T is an IKE phase 1 algorithm that is used when trying to establish a VPN between two gateways devices where a NAT device exists in front of one of the devices, in this case a Juniper Firewall device. They are set up in a hub vpn on the template, the office subnet is set to use VPN as is the client, with automatic NAT traversal. While the VPN's show as established in the VPN status page for the devices, I cannot ping across by name or IP address. By "see" I mean I cannot navigate to \server\share in Windows Explorer. Jan 13, 2016 · Note: An ACL for VPN traffic uses the source and destination IP addresses after Network Address Translation (NAT). Note: An ACL for VPN traffic must be mirrored on both of the VPN peers. Note: If there is a need to add a new subnet to the protected traffic, simply add a subnet/host to the respective object-group and complete a mirror change on Site-to-site Status Active Connection Delete Wizard Manage a Name XG UTM Group Name Network Details IP Family * Local Local Subnet NATed LAN Local ID Remote Allow NAT Traversal Remote CAN Network * Remote ID 1 pve O IPvô HO XG LOCAL Remove Same as Local LAN address Select Local ID Enable BO UTM REMOTE Add New Item Select Remote ID Jul 26, 2017 · In this blog post, we're going to walk through NAT Traversal and the different considerations to think about when a firewall is in the path of the VPN peers. I'm going to use the same configuration from the previous site-to-site IOS VPN blog post but with one difference: I've placed an ASA in the path with PAT configured on it. NAT traversal is a feature that allows IPsec traffic…to pass through a NAT or PAT device…and addresses several issues…that occur when using IPsec.…The Authentication Header provides connectionless support…for data integrity and authentication of packets.…The Authentication Header authenticates…as much of the IP header as possible Dear Sir, My scenario is that I have two 4g internet connected to one device MX64 to wan1 and wan4, and configured as site to site HUB vpn, with Automatic NAT traversal. And another MX64 device with another 4g internet connected to wan1. And configured as site to site spoke VPN to the first HUB
Your Site-to-Site VPN connection is either an AWS Classic VPN connection or an AWS VPN connection. Any new Site-to-Site VPN connection that you create is an AWS VPN connection. The following features are supported on AWS VPN connections only: NAT traversal. 4-byte ASN (in addition to 2-byte ASN)

Scenario: In this example two FortiGates in a site to site example will be used, where Site A will initiate an IPSec Policy Mode tunnel to Site B, and Site B will receive traffic from Site A …
