How to connect to a specific server that has 192.168.0.X IP

[abobo78]

Hello everyone
I'm following a simple guide on the internet about how to create a local server for a specific game on a virtual machine
I did all the steps without problems, but when I test, I can't connect to the server
Someone told me it's happening because my virtual machine IP is 192.168.0.X and it should be 192.168.1.X
I tried to set a static IP, but this didn't work
My question is: How do I make it work using 192.168.0.X IP?
Thanks in advance.

This is the guide I'm following:
Step 1 : Create the linux and prepare it
1) Create Virtual machine on Virtual box with this setup
- core : 2
- ram : 4 gb
- disk space : 50Gb

2) Install Ubuntu 20.04.4
- You must install SSH

3) Execute the following commands

- sudo apt update
- sudo apt upgrade
- sudo apt install nano 
- sudo apt install net-tools
- sudo apt install screen
- sudo apt install unzip

4) Enable root login over SSH using

- nano /etc/ssh/sshd_config
- Change or add line: PermitRootLogin yes

5) Then restart SSH service
- service ssh restart

6) Then setup database
- sudo apt install postgresql

Step 2 : Setup the postgres database
1) Change your user to postgres

- su postgres
- Then write: psql ALTER ROLE postgres WITH SUPERUSER INHERIT CREATEROLE CREATEDB LOGIN REPLICATION BYPASSRLS PASSWORD 'test';

2) Allow the login from external

- cd /etc/postgresql/12/main
- Then: sudo su
- Then: nano pg_hba.conf
- Change this: host   all   all   127.0.0.1/32   md5
- To this: host   all   all   0.0.0.0/0   md5
 

3) Update postgresql.conf

- nano postgresql.conf
- Change this: #listen_addresses = 'localhost'  # what IP address(es) to listen on;
- To this: listen_addresses = '*'  # what IP address(es) to listen on;

4) Restart postgres
- service postgres restart

Step 3 : Setup the database
1) Change to postgres user

- su postgres
- Copy your database.out to the VM in the folder /home

2) Then:

- psql -f database.out
- Copy your worlds.sql to the VM in the folder /home

3) Edit the worlds.sql following your local IP

- INSERT INTO "public"."worlds" VALUES (1010, 'CHANNEL_NAME', 'YOUR_IP', 5712, 0, 150, 1, '002.003.05.67', 1, 0, 1, 100);

4) Then:

- psql -d fnaccount  -f worlds.sql
- Copy your serverstatus.sql to the VM in the folder /home

5) Update serverstatus.sql following your IP

- INSERT INTO "public"."serverstatus" VALUES (1010, 'WorldServer', 'YOUR_IP', 5712, '127.0.0.1', 5712, 0);
INSERT INTO "public"."serverstatus" VALUES (1011, 'ZoneServer', 'YOUR_IP', 10166, '127.0.0.1', 10166, 0);
INSERT INTO "public"."serverstatus" VALUES (-2, 'MissionServer', 'none', -1, '127.0.0.1', 7654, 1628266391);

6) Then:
- psql -d fndb1 -f serverstatus.sql

Step 4 : Launch the server

- Copy paste server folder in /home of your VM
- sudo su
- sudo chmod 777 /home/server -R **
- Change all password database in files
- Start the server with: ./start

How and from where are you trying to connect?

Why does it have to be 192.168.0.X? How do you know if it hasn't been already allocated/assigned/in use?

Step 4 : Launch the server

Does it say something like server is up and running and says any IP/port number?

Not this use case specifically (Postgres server). Long ago, I used NAT (Metasploitable or Kali VM, if I remember correctly) to set up a lab.

The disadvantage of NAT mode is that, much like a private network behind a router, the virtual machine is invisible and unreachable from the outside internet. You cannot run a server this way unless you set up port forwarding.

Might be useful to you.
