If you don’t have any of those going on, then you should always set your port lockdown settings to “allow-none”. This is only useful for a few scenarios like – connecting to the self IPs as mgmt interfaces (a big no-no), iQuery ® traffic, HA / Sync traffic, IPSEC termination endpoints. The port lockdown setting is to allow connections to “terminate” on the individual Self-IPs. In particular, folks think they need to allow specific IPs & ports in the port lockdown settings for traffic to flow through your self-ips – this is not true. This is one of the most misunderstood settings on the F5 LTM. The LTM interface gives you a “port lockdown” setting that allows you to accept or deny traffic on different ports. You can think of them as your next hop interface, and or your exit interface. Typically your Virtual IPs live on the subnets Self-IPs are a part of. Self-IPs – These are logical interfaces you assign for data the BIG-IP pushes.Authentication can be local or to some sort of directory service like LDAP / AD. This interface is typically an RFC-1918 private address and should never be exposed on the Internet. By default, the management interface listens on port 22 for SSH and port 443 for HTTPS web access. Management Interface – This is how you administer the F5 and is a physical ethernet port on the F5 BIG-IP hardware devices, and a logical interface you assign to a NIC on the Virtual Edition Devices.
Let’s evaluate all the ways traffic can enter & exit the F5 BIG-IP LTM Module: There are only so many entry points into the F5, and unless you open them explicitly – there is no way for traffic to enter or exit the device. What you may not realize is LTM is indeed also an IP & port based firewall. From terminating and offloading SSL / TLS Traffic and simplifying certificate management, to load balancing traffic based on performance to monstrous server farms – LTM is the most complete Load Balancer on the market.

Enterprises use LTM’s full proxy functionality to offer complete control to their application teams with the ability to augment client side and server side connections independently. Like all of F5’s products, LTM works in on-premise hardware as well as all the popular clouds like AWS, Azure, and Google Cloud.
LTM is the core module included in base “Good” licensing platform F5 offers. In this article, I’ll break down all the different ways F5 is a firewall – making it the most advanced and complete firewall on the market today.
Even the base LTM is indeed a traditional IP & port based ICSA certified firewall, and has been since 2011. While this is progress for sure, what most people don’t realize is all the modules in the BIG-IP family are security focused and offer some type of firewall functionality. Now, in conversation when you tell people you work with F5, more often than not they say “oh yeah the WAF company!” This wasn’t by mistake, since the BIG-IP ® is the best in the industry at terminating SSL / TLS, it makes it easy to see unencrypted traffic and apply security policies to it like a WAF, or identity and access rules with the APM ®. the Application Security Manager ™ (ASM ®). Many of us first discovered F5 ® because of their flagship LTM ® & GTM ™ products, but more recently the F5 firewalls have been making waves, namely their Web Application Firewall (WAF) a.k.a.
