disregard, fixed via port forwarding and outbound.

Earlier today out of frustration, i wiped my OPNsense box.

i then reinstalled fresh off a new USB image, 23.7. then followed with the system update to 23.7.12.

after the system update restart, i fixed my PPPoE on my WAN interface so i would get internet, it came up 5 seconds later, i then reinstalled os-upnp and rebooted again after enabling it.

i then opened up steam on my gaming PC, left the "status" page open for UPNP on my other monitor, and launched anno 1800 , i saw no UPNP port mapping pop up and was met with strict NAT.

is there a way to solve a strict NAT on opnsense? i only need it to function for a single PC, no consoles or anything of the like as of yet, as i am currently renovating my home.

any help would be greatly appreciated,
i will note anno 1800 is the fastest launching game that shows NAT status that i have, the same NAT status is also displayed in call of duty, PUBG, and a few other titles.

[advanced DMZ]

hi, thank you for responding.

it is not to replace my own PC's firewall, my pc runs bitdefender and always has, its never been an issue.

the WAN IP comes from my ISP, the opnsense box is hooked into my ISP modems 10G port, and is passed through via advanced DMZ, its the only way i could get the wireguard for my game server to function properly and allow connection.

i do have a pppoe setup on the opnsense box aswell that will also get a direct WAN IP seperate from the modem if i need to go that route.

to make clear, opnsense is in place to be my game server's firewall, the only thing it uses a wireguard tunnel for is a static IP.

if any other information is needed, let me know and ill be sure to post it.

Hi, all i recently setup an opnsense box to give my game servers an extra layer of security, but i need to punch through the strict NAT on my gaming PC to play games i have tried the following:

1. installed and enabled UPNP, rebooted opnsense box and pc to test. no ports registered in UPNP status page, strict NAT

2. left UPNP enabled, added allow rule for PC IP, setup outbound rule. no change.

3. made a crude attempt at port forwarding all ports for my PC that i could remember were used for games (even tried 1024-65535 for a laugh) no change in NAT.

i'm totally at a loss here. i will attach images of the outbound/ port forward rules i created and enabled, as well as my upnp config page below.

any help would be greatly appreciated, i've been at this for 2 days now.
