i think you had better also check uri.

e.g.

when HTTP_REQUEST {
  if { ![IP::addr [IP::client_addr] equals 10.1.2.0/24] and [HTTP::uri] eq "/" } {
    HTTP::redirect "http://[HTTP::host]/cams"
  }
}

No luck. I have tried enabling logging and found the irule is not detecting the ip address.

when HTTP_REQUEST {log local0. "before ip" if { ![IP::addr [IP::client_addr] equals 10.1.2.0/24] and [HTTP::uri] eq "/" } { log local0. "after ip" HTTP::redirect "http://[HTTP::host]/cams" } }

I am getting only the "before ip" in the logs. Seems like the if condition is not matching.

I tested this in my lab now, and it works fine. My BIG-IP is running version 12.1.2 (Build 1.0.271).

Can you start a tcpdump and verify that the source IP (client side) actually is what you expect it to be?
