I’m kinda stuck on opensense. So i’m in need to portforward some new servers, the problem is my isp’s router webui, apparently they removedthe ‘save’ button, meaning that I can add a port forward but not save my configuration. since the issue is already ongoing for more than a year, I tought to build my opensense and put the opensense on dmz of my isps router.

isp router is at 192.168.0.1
lan is at 192.168.0.*
my pc: 192.168.0.195/16
opensense wan ip: 192.168.0.227/16
opensense lan : 192.168.1.1
satisfactory: 192.168.1.97/16
factorio: 192.168.1.80/16

tests: internet connection, icmp, portwarding for the game servers.

I rather left opensense as the dummy intallation, I unchecked block private network, i disabled ipv6 and changed my dhcp address to static 192.168.0.227/16

I tought I had to use 255.255.0.0 rather than 255.255.255.0 to access multiple subnets.
The game server are vm’s on a vswitch with an uplink directly connected to opensense (physical server)

I created the port forwardings using the docs and tutorials. (not into networking, developer 🙂 )
I created an any any rule for icmp as I wanted to ping from and to for everything (testing purposes)

My pc 192.168.0.195 can ping to opensense 192.168.0.227
my satisfactory server 192.168.1.97 can ping to opensen 192.168.1.1
but my pc cannot directly ping the satisfactory server
my satisfactory server can ping google dns
my satisfactory server has access to the internet as apt update && apt upgrade was working.

However when launching the game from 192.168.0.195 it could find the running server.

Today I tought to try to test with my factorio server since this is only 1 port forward,

I put my factorio server at 192.168.1.80/16
But for some reason this doesn’t have an internet connection, i checked both netplan yaml files and made them the same accordingkly, but still no luck.
my factorio server can’t ping google dns
my factorio server can ping opensense and can ping my satisfactory server and vice versa.

my netplan config:

my port forwardings:

The question is:

1. why does my factorio server haven’t any internet connection
2. why can’t my server ping my pc and vice versa
3. what is worng with my port forwardings, or ( I assume they are correct but there is no communication between the 2 networks)
