Proxmox ubuntu vm in virtualbox internet access problem

[haderach]

Hello guys. I know that this is recurring question, but a really red a lot of articles and solutions and none of them works. Maybe i miss something. I will describe what i done by now.

• Configure virtualbox with bridged adapter ( i know that on wiki suggest to use nat, but i found some solutions, using bridged)
• Install successfully proxmox. The ip was by default 192.168.0.109. From proxmox console i have internet access.
• Then i create vm ubuntu 24.04. I try to follow auto network configuration trought the installation process, after that i try manually to configure - same result. Now vm ip is 192.168.0.150 with gateway 192.168.0.1 (the routher default gateway).

From the vm i dont have internet access. I do have access to proxmox env, when i ping 192.168.0.109. The proxmox also ping the vm. From the vm i cant even execute apt update.
Sorry for the repeated post, i know that here have other on that subject, but i really dont know what can i do about it. Really im not network guru .
