IP Tables (Kali Linux)

I’ve encountered an issue upon setting up IP Tables in Kali Linux following along with Volume 2: Network Security. In Section 4 Video 20, I entered the same commands and set up my IP Tables Configuration exactly the way shown in the lecture. However after doing so, I couldn’t seem to connect using the wget command and even trying to reach a webpage in the firefox browser showed an error and wouldn’t connect. I will provide screenshots of the commands/rules I entered and the errors I received upon attempting to connect. Maybe I’m encountering this error for a reason I’m unaware of. Thank you in advance for any replies! IP Tables Rules
