ACL for allowing basic protocol only

[techguy]

Anyone who can share or suggest to limit users downloading/buffering/streaming/torrents etc and to allow only standard protocols over the WAN link.

Thanks,

On your edge routers you can deploy ACLs to allow for example only http and https, but  if your users need to use other port/protocols, you would need to allow these as well.

Have a look at this link for examples;
