ELB Rule if Host Header is not equal to

Question

I am looking to write a rule for ELB that redirects to a certain host, if the Host Header does not match that host. The use case is trying to access to the underlying site using the IP address and not the domain name.

I have it working if I manually do if HOST HEADER = {IP ADDRESS} but this isn't ideal as any time a new network interface is created or IP address updated I will need to update the rules.

Is there a way to do != in the value for host header?

Answer

Hello

As far as I know, there is **NO possibility to use not equal in ALB rules**, But there are some possible ways you can use it to work permanently.

Possible solutions:

*  You can Create a Lambda function that will trigger when new Network interface is created and update it in the ALB host headers
*  You can also use[ Lambda function as a target to your load balancer ](https://aws.amazon.com/blogs/networking-and-content-delivery/lambda-functions-as-targets-for-application-load-balancers/#:~:text=As%20of%20today%2C%20Application%20Load,from%20web%20browsers%20and%20clients.)
