Beginner config questions

Almost have my router setup, but can’t figure out how to do a few things:

1.) How do I limit total p2p traffic for all users to a maximum of say, 256kbps?

2.) How do I NAT port 23 from a private IP to a public IP?

3.) Any recommendations to ensure I don’t receive the dreaded Strict NAT type when gaming?

Thanks in advance!
