Do we need EA Tunnel and UpnP?

My gameplay is regularly awful. 

I was wondering as a test to see if there's anything my end I can do as a last resort after test after test of my ISP saying everything is fine. 

Do you use EA Tunnel? do you use DMZ? or UPnp? 

I'm on PS5 located in UK. 

Probably a question for those who don't have gameplay issues
