Windows 2012R2 VB Host 20.04.x Ubuntu Guests cant ping past gateway
by gkasica from LinuxQuestions.org on (#5C16J)
I've had Virtual box running here for years on Windows 2012R2 with a couple of Ubunto Guests. I just made 2 new 20.4.x guests in preparation to upgrade mail servers. Neither system can ping past the gateway and obviously, I can't connect to the repositories to update or install anything. I'm using Bridged and see the gateway and ping it but nothing past it. The ISP is Spectrum and I have a block of 29 usable addresses. Other things like me AppleTV have no issues. I'm stumped here is this an Ubuntu VM setup issue(version 20.04.x}, Windows 2012R2 or VB issue (version 6.1.16). This configuration was flawless on 18.04 and once we put in Spectrum Internet it all went south. I can ping the spectrum gateway from Host and Guests but can't connect or ping past it from the VB Guests. The host has no issues. All the other physical devices can connect and ping normally including the VirtualBox Host on Server 2012R2.
What information do you need to see here to assist? I don't have access to things like route or ifconfig as they are in the net-tools package and I can't get to the outside world to load anything.
