We have f5 in dual arm. SNAT is being used. If I use iRule to extract client ip address at the time of connection, will it work? Or is there any other way to pass client actual ip to backend?
Unfortunately iRule won't work. You are able to get the client IP but you only can add it to a header information.
thanks for the reply. You means to say that we can’t pass it to backend servers? Only f5 will have those ips?
Yes, If you need to see real IP on this scenario, set your server's default gateway to F5 floating IP address and disable SNAT.
