Can I have multiple VMs share internet access off one NIC?

[jumpin_jamie]

I want to use 2 (possibly more in the future) virtual machines with internet access off of one NIC. I have one default gateway from my network router. I use the default vmbr0 running off of the eno interface (as seen in attached images) to share internet access. Both VMs use the same OS and they both share vmbr0 in their configurations. When the OS is setup, only one is allowed to use internet access and the other just says no internet. Is there a way around this or do I need to do some more proxmox config. If so please explain in detail as I am a bit of an ameteur. Thank you!

You have set different MAC adresses for your 2 vms, which is correct, do you use DHCP in you vms or are you setting static IPs?
You have to configure your Router as default gateway in both machines, give them different IPs inside in your Network and set the DNS nameserver, probably to the IP of your Router, too. Try to ping the IP you of your router simultanously, it should work. If it works try pinging 8.8.8.8 (Google DNS)
then try DNS name resolution via host heise.de for example

I run 5 different VM's off one host with one NIC. As long as you take throughput/bandwidth into account, you're good
