This solved my lag issue!!!

Whoa... 443 is the port used for secured HTTP (a la https). It is a really bad idea to blindly port forward this... Just saying...

Your concerns are in the right place. I am opening these ports for my PS3 and PS3 -only-. Should be more than safe, I can't lose much, even if it's a scam. One-time password and all.

If it doesn't work, I'll close the ports back up and report here again.

Trying this personally, will report back.

Confirmed. Opening these ports did NOT I repeat, did NOT fix my pop-in issue. I strongly advise against doing this due to the security risks.
