Pin On Nat Hair pinning also known as nat loopback is a technique where a machine accesses another machine on the lan or dmz via an external network. traffic goes through the lan interface to the internet, then goes back to the same interface, connecting to it is external ip. traffic is then forwarded by fortigate through a virtual ip to the local. In this configuration, the internal address of the server is 192.168.10.4, and the external address is 98.174.86.3. i don't know if that corresponds with your real web server address, since you have several static nat translations configured, so you might need to change the addresses accordingly: interface loopback0.
Pin On Nat Alia First of all, such a situation is encountered often enough. second, while nat theoretically may be a solution, in practice particular vendor implementations of nat can be restrictive and fail to support this. one typical solution is to address the server located in the internal network by fqdn, not by the ip address. B. the makeup of your destination nat rule ( is it formulated for the type of wan connections you have (static vs dynamic). c. srcnat rule for hairpin nat added to the config. remember hairpin nat is only needed if the users and server(s) are in the same subnet. one can always consider moving the servers to a different subnet. How to configure hairpin nat in fortigate firewalldebug logs for the hairpin nat session information for the hairpin nat techtalksecurity. Nat nvi (nat virtual interface) can handle even complex nats, zbf (zone based firewall) is a nuanced and fantastic way to handle access control, etc. hell, you can even build anyconnect on ios these days! but there's one problem that is intractable on cisco's ios platform: hairpin nat. because this problem is called so many things, let's define it.

Configuring hairpin nat (vip) in fortigate. hair pinning, in a networking context, is the method where a packet travels to an interface, goes out towards the internet but instead of continuing on, makes a "hair pin turn", and comes back in on the same interface. initially, it may seem unnecessary or pointless even but it does serve a purpose.
