port triggering problems on SWBF2

So I have 2 PCs in my house both wanting to play the game together we periodically get disconnected and error 327 I'm told to port forward on my router but port forwarding on my router will only allow port forwarding on one device using the same ports for both IPs cause port conflict. as far as I have read I need to use port triggering but I can't get any help from EA on port triggering so I'm lost...

I'm running a Netgear Nighthawk r7000
