I have several VMs in the same virtual network using the network configuration of static IP through Azure. I have a DNS server in my VNet as well.
Two of the VMs cannot access the internet for some reason. They receive the same DNS configuration from Azure which is my DNS server.
DNS resolution works just fine however I cannot access the internet at all and cannot ping anything outside the VNet.
I added an outbound port rule to allow http+https connectivity and the connection troubleshoot from the portal to those machines works.
Firewalls are off.
No proxy settings in IE.
I have no idea what I am missing.

If it is a standard load balancer that is probably is it, I’ve seen it before and is apparently by design as discussed here
You are the man :-) A small detail I forgot to add and research, thanks for the help!
I will update this post with my solution when I resolve this issue as well.
Hi,
Please check if this is due to any incorrect Windows firewall rules. You can test it by temporarily disabling Windows Firewall on those two machines

Firewalls are disabled, I mentioned that in my post :-)
Hello,
Apology for not noticing the Windows Firewall status you mentioned in original post.
I am seeing that you just enabled outbound port access for http and https as mentioned in your post. Actually, inbound port rules also need to be changed for these protocols. Could you please check that too

Are you sure about that? I'm asking because the other VMs does not have this rule but they can access the internet still :[
Hi,
I am not sure how the other VMs can work without an inbound port rule. Usually, when you setup a port access, inbound+outbound is defined in combination
Thanks,
Manu
OK. so that did not help either :<

Does it work with defaults?
Control Panel\System\Windows firewall\Advanced then in right hand pane Restore Default Policy

Hello,
I think, you may go for detailed network check as the conventional troubleshooting steps didn't help. Please check the link below and have a detailed check
