open port on 50E

Hello to all, I recently took possession of this fantastic 50E firewall, we had it in the company where it was managed by more competent external people.

i tried to configure the ports as in every guide in the network also watching many videos, but nothing i can't get anything to work. being at home I don't have a corporate internet .. so I have a dynamic ip and a modem .. with the affected port open.

my firmware version is 6.2.5, I create a VIP with:

NAME:mywebserver

0.0.0.0 External IP (I also tried to put the IP of the modem to which I then connect externally 192.168.1.204 or my external IP)

192.168.0.106 Internal IP (my server web)

Wan1 For interface (modem internet) (i tried to put lan and any)

TCP PORT 8182

then I created an IPv4 rule:

Incoming Interface: Wan1

Out Interface : lan

Source: all

destination: "mywebserver" (I also tried to put all)

Schedules: Always

Service: ALL (I also tried to change the server ports by putting 443 and then selecting HTTPS)

Firewall NAT: ON (I also tried with OFF)

Security profile: All off (here I have a big problem I can not remove the ssl but I did not check the certificates)

ok, yes I tried in all ways without results, obviously the firewall is practically new without any changes .. I formatted it .. changed password connected to the modem and connected to the pc.

can someone help me? did i do the right procedure? before that i used another firewall and everything worked (it was from another brand)
