run web server behine router

[Kevin D. Goodknecht Sr. [MVP]]

Come on, guys, stop. Please do not talk about China, we are in USA.

I do not care about their contract, yet. All I want right now is to
prove that I can setup a server and people can access it. It seems to
be true because if I take out the router, everything works fine. Now,
my problem is how to run my server behind router? Did anyone find any
trick that is not commonly known?

Please help with my problem.

It seems to me that your problem is with Cisco, and you're not the only one
I know of using this router that has a problem with this same issue.
