Internet access in "NAT network" mode doesn't work in Ubuntu LTS 16.04 and LTS 18.04

[Alex]

First, thank you for your work.

Second, excuse my poor English.

Third, this is not the same bug that https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1621890

Summary:

At least in Ubuntu 16.04 LTS and Ubuntu 18.04 LTS the mode Nat Network of virtualbox doesn't work properly:

The virtual machines in the same Nat Network can see each other, but none of this machines can access internet.

File /usr/lib/virtualbox/VBoxNetNAT exist, is not missing, that is the difference with bug # 1621890

Install virtualbox from Oracle repositories fix the problem.

Status changed to 'Confirmed' because the bug affects multiple users.

[Edison (ooknosi)]

The default initial NAT configuration on adapter 1 grants Internet access.

When switching to NAT network, Internet access is lost.

Internet access is not regained by switching back to NAT.

Can you please try again with 5.2.34 in bionic?
I think I fixed bug - Add suid bit to VBoxNetNat to make it work (LP: #1805651)

in 5.2.32 already on Thu, 18 Apr 2019

I checked on Ubuntu 18.04 upgraded to 21/11/2019, that means virtualbox 5.2.32. It works perfect now. Problem solved! Virtual machines with NatNetwork mode accesing internet.
