PT-cloud or port forward nvr?

Hello I have a new LTS Nvr that supports pt cloud. Have some questions. Should I use PT-cloud on the nvr or port fwd nvr?
For remote Internet access What ports are needed to port fwd the nvr? I see the lts cams also have pt cloud support, should I enable them also or not needed if using pt cloud on nvr.
Thanks

Anyone try PT-Cloud?

None of the above.

Use a VPN. Your router likely has VPN server capability built in. You are drastically less likely to be hacked if you use a VPN.
