GTA IV PC Strict NAT

Hey folks i seem to be having an issue with GTA IV PC Vanilla and EFLC with the game saying i have strict NAT.
 

Im fairly competent at networking concepts so i under stand how port forwarding works ect...

FYI my router is an old PC i had, It's running OPNSense (similar to pfSense) and i have tried port forwarding the ports R* says in the PDF manual as well as what i've also seen from googling and a few posts here.

Here is a screenshot of what i mean, the interesting part is says it has found 19 results but wont display them.

FYI this was done with my Windows firewall temporarily disabled.

Here is a screenshot of how i have it at the moment in the port forwarding table:

Port forward

 

My PC has the local IP of 192.168.1.15 which i made a static DHCP to my PCs NIC Mac address.

 

Anyone know whats going on because as far as i can see it should be okay, i know this game is notorious for having MP issues but that's usually when your mid game.

Forget about the bloodshed my dudes! 😎

Not sure if it might help, but enabling UPNP might? My NAT goes from Moderate to Open when I do so.
