Can access web GUI but no Internet

[dev.leee930]

Hi all, I am a newbie to networking and to proxmox so please bear with my questions.

I have installed proxmox and I was able to access promxox via the web GUI just fine.
However whenever I try to apt update or ping say 8.8.8.8, it's unreachable.
I have dig through many threads and try different settings and nothing seems to work.

I am directly connecting my device to the modem ethernet port instead of to the wifi router. Does this matter?

here's my settings. thanks in advance!

Hi,

Can you ping your gateway ?

Also, why are you masking your IP (which should be on private range) ?

Best regards,

Best regards,

I get "Destination Host Unreachable" when I tried to ping my gateway.

I masked it cause it seems like it's a public IP. It doesn't fall into these range

• 10.0.0.0 to 10.255.255.255
• 172.16.0.0 to 172.31.255.255
• 192.168.0.0 to 192.168.255.255

Is it normal? I got my default gateway value from my router's (192.168.68.1) configuration page.

if you are using /24 subnet, then the leading first 3 segments of IP / Gateway need to be the same.
Example:
192.168.68.1 gateway, usually router LAN ip
192.168.68.10 pve

The IP range should match a private IP range.

On the LAN side of your router, no.

We need your complete network setting (without masking) because it seems something is not right on your configuration.

Best regards,

It might, your provider may be limiting the access based on MAC or other factors.

Unless this is a business connection his provider almost certainly does not want him to set a static IP. In the case he has done that (rather than DHCP), the provider is going to block him.

Thanks for all the help!

this seems to be the problem I was trying to set a static IP but it just ain't possible.

I followed the solution from another member https://forum.proxmox.com/threads/p...rk configuration,I get a different nameserver

Now I finally have Internet access. But my guess is if I have a power outage or my modem reboots I will lost access as the IP will be reassigned?
My next question would be is this solution not the best practice? is it better to plug to a router to obtain a private IP instead of directly to the modem?

Probably.

I guess that depends on whether you are comfortable allowing anyone, anywhere, to try to hack your server. Putting your server's management interface on the public internet with no firewall is very far from best practices in regard to security.

Why do you want this? That is the question that needs an answer before people can give advice.
