Problem with connection to internet by VM with private IP

[mateuszs]

Hello Guys
First Thank you for answer and sorry for same topic. I spent a lot time for search solution for my problem.
I am making this thread becuase I have no idea for my problem.

Simple problem "My new virtual machines doesnt have connetcion to internet"

I tried solutions from:

https://pve.proxmox.com/wiki/Network_Configuration

1. I tried this configuration for make internet connection for my VM

2. Same I tried: Masquerading (NAT) with iptables


And no results.

My configurations:


When i try setup network configuration by manual in Ubuntu 18.04
I dont have connection to download files for system from mirros


I would like to setup privates ip for virutal machines with internet connection

When i try setup in Ubuntu

Do I read this right that your host sits directly reachable in the internet?
If so you should really re-think your setup.

You can't use private IP addresses without a router/NAT/gateway on your end.

I am using PFsense for this purpose and can recommend it. Opnsense is another good solution and there are tons of alternative ones.

Its only fort tests and teaching my self

Correct?

 

[apoc]

Imho That configuration is nonsense (unless you have set up routes that tell your 200.0../22 network where to find the gw 193...
How should the system reach that IP? Its beyond the network...
You need to have a gateway within your network.

OK sorry! my bad

What do you have in the /etc/resolv.conf file ?

 

[mateuszs]

 

[dako]

Change to
nameserver 8.8.8.8 nameserver 8.8.4.4
or
nameserver 1.1.1.1 nameserver 1.0.0.1
and see if it works.

 

[mateuszs]

nope, same problem

My configuration:

When I configure by ubuntu install i set adres ip 10.10.10.2 and nameserver 8.8.8.8 8.8.4.4 for my vm

 

[dako]

have you provided /etc/resolv.conf on a VM or proxmox machine ?

 

[mateuszs]

Yes, i set in proxmox server:

Sorry for this:
if you would like
I can give you access to my proxmox and ssh and you can try it.

 

[dako]

Set to VM.

 

[mateuszs]

I had IT by automatically

 

[dako]

You should have
address 193.107.91.45/22
(without netmask) or
address 193.107.91.45
netmask 255.255.255.255.0

Classless Inter-Domain Routing already determines what the mask is.

 

[mateuszs]

Same problem

Look for my configuration step by step

 

[dako]

I mean the configurations eth0

 

[mateuszs]

Look i have

 

[dako]

Did you reboot the proxy after the changes ?

 

[mateuszs]

Yes

I used shutdown -r now for sure.
The machine has reset and i have new set up.
