Dec 10, 2017 · I use two distinct rules as egress (from internal network to vpn clients) could be a different set of rules than the ingress (from anyconnect clients to internal network). Configure the rule and policies as needed. Hairpin NAT & traffic. It is possible to execute hairpin NAT on FTD.
In network computing, hairpinning (or NAT loopback) describes a communication between two hosts behind the same NAT device using their mapped endpoint. Because not all NAT devices support this communication configuration, applications must be aware of it. Apr 02, 2013 · In another article, I provided an example using an IOS based device to hairpin traffic between a VPN spoke and the Internet. This article simply provides a commented solution to the challenge of routing Internet bound traffic through an ASA based IPSec VPN. In this article, the firewall is running version 8.4 of the ASA operating system. Jun 20, 2014 · This document describes how to set up a Adaptive Security Appliance(ASA) 8.0.2 to perform SSL VPN on a stick with Cisco AnyConnect VPN client. This setup applies to a specific case where the ASA does not allow split tunneling, and users connect directly to the ASA before they are permitted to go to the Internet. However, with this version the intra-interface-parameter was only functional for vpn-traffic, for example traffic from an outside vpn-client destined to internet (full tunneling). ver 7.2. Beginning with v7.2 the “same-security permit-intra-interface”-command becomes useful and can be used for other traffic than vpn-initiated. Now we can do Traffic between Branch 1 and Branch 2 should be able to talk across the existing IPSec VPN on headquarters ASA (HQ). Concepts : Hairpinning (U-turn Traffic): Hairpinning is a term to describe traffic that is routed out of the same interface from which it entered.
The ASA supports a feature that lets a VPN client send IPsec-protected traffic to another VPN user by allowing such traffic in and out of the same interface is called “hairpinning”, this feature can be thought of as VPN spokes (clients) connecting through a VPN hub (Cisco ASA firewall).
Hotspot Shield is an awesome free VPN that has helped millions of people in their time of need. It was the most used VPN during Asa Anyconnect Vpn Hairpin the Turkey coup and the Arab Spring. Users get free access not only to the VPN but also a Chrome extension. This removes the need for a hairpin through the VPN/corporate network for general browsing traffic, whilst still allowing central security control. Even with these solutions in place however, Microsoft still strongly recommends the Optimize marked Office 365 traffic is sent direct to the service.

NAT Hairpin Hello, I need inside hosts to access (from the inside network) by the Wan IP (external IP) an inside (mapped) IP. This is known as NAT hairpinning or NAT reflection. I did not find any document about this in fortinet. Others vendors support it. Can anyone point me to a configuration? Thanks in advance.

I have an XG-7100 with IPSEC VPN to two other sites, as well as Azure; call them Main, North, South and Azure. I've observed: bi-directional traffic between North LAN and Main LAN bi-directional traffic between South LAN and Main LAN bi-directional traff How to configure NAT Loopback (Hairpin NAT / NAT Reflection) To resolve the issue with the traffic flow between Client #2 on an internal network and the Web Server, an additional NAT rule needs to be added on the Security Gateway to perform NAT on this traffic as on the traffic between Client #1 on the public network and the Web Server. So the idea is to port forward to the 2611, however I am not sure how to get the VPN traffic back, I have two Ethernet interfaces on the 2611 (FE WIC) can I send one back to the SOHO router so that it can access the network, or can the VPN traffic come in the same interface as the non-encrypted LAN traffic? Slow traffic speed (high latency) when transferring files over VPN tunnel. Output of 'top' command shows 100% SoftIRQ during the file transfer. Output of 'top' command shows that CoreXL FW instance 'fw_worker_X' consumes CPU at 100% during the file transfer. Issue occurs regardless of the status of SecureXL. May 07, 2018 · Typically NAT is used so that machines on a private subnet (10.*.*.*, 192.168.*.*, etc) can share a single public IP address. To do this when a private machine (say 192.168.1.100) makes a connection to a public server (say google.com) the Untangle server rewrites the source address to the public IP address of Untangle (say 1.2.3.4) on the way out. NAT hairpinning is a useful technique for accessing an internal server using a public IP. In order to ensure that the flow occurs properly: Both the source and destination IP addresses need to be modified so each device sees the traffic flowing to and from the correct locations.
