Port forward not working

Hello.

Vous pouvez répondre en français. Je peux bien le lire mais l'écriture est plus difficile.

I have trouble forwarding port 34197 on my router.

- I allowed the port in my PC's firewall (inbound and outbound)

- My PC's IP is reserved in my router and /ipconfig confirms it's correct.

- Port forwarding rule in router is set to the local IP of my PC and external IP is set to 0.0.0.0 (forward rule is also Enabled)

- subnet mask in PC is 255.255.255.0

- In the router I also see subnet mask 255.255.255.0

- default gateway in PC is 192.168.0.1

- router's LAN IP is 192.168.0.1

- DMZ is disabled

- router's firewall is set to 'low' although 'disabled' didn't help either

- router's WAN does not start by 10.x.x.x

- router's WAN IPv4 address corresponds with what https://www.yougetsignal.com/tools/open-ports/ tells me my IP is, so I have a public IP

Why is it still not working? Did I miss something?

I contacted Voo support and they checked my router's settings and they said everything looks fine for them. They can't solve the issue for me.

Thanks in advance!
