Port forwarding alone requires your main computer to have greater security measures in place because you've essentially opened the door for anyone that can access the remote device or computer and would highly recommend a VPN as well. Someone can hack into the connected device and enter through the forwarded port. BUT port triggering, like a doorman at a club, would keep that door/port closed until you needed to access it which protocol would let you in the door to the bar with the proper ID to have that drink but not the patrons without ID that don't belong to this club. Keeping out the riff-raff.

You can boost the Ethernet’s capacity by wiring switches to each other. Unlike routers, Ethernet switches use multiple ports to enable devices in the LAN. Unmanaged switches are a type of plug-in switch that will work when connected, without the need to configure them...

Greater security concerns would require port triggering.
@Michael Carter Thanks. Would you mind elaborating a bit more? What sort of security concerns would require port triggering?
