Cannot access some HTTP:// sites from within a standard virtual machine on Orcon.

Orcon UFB under UFF (Hamilton)
Orcon "white" NF4V

Apart from a couple of port forwards (and therefore admin interface on LAN port 8080), left basically standard.

On a machine in the network.
Windows 10 pro virgin install.
Hyper-V
Single "external virtual switch", no vlan tagging.
Windows 2012 trial (from Microsoft's VHD)

- gets it's ip VIA DHCP from the NF4V (reserved by MAC address)
Regardless of browser, On the W2012 I can access only some internet HTTP:// websites.

eg:      Cannot access www.bing.com, but can access https://www.bing.com
    Can access http://www.google.com and https://www.google.com

The host machine can access any of these sites.


Tried:
I've turned off smartscreen, browser protection, etc.
opened, and even disabled the W2012 firewall.
Switched to VMWARE player.
Switched to a different host (A Win7 one).
Configured windows on the VM to use a proxy (and set up CCproxy on another host in the network).  This works, but does not solve my problem.
Set the VM to use the host's WIFI, and tethered to my mobile phone.  This worked too but does not solve my problem.
Messed with many settings on the NF4V, but set them back when nothing worked.
Called Orcon.  They said "Virtual networks / machines are not supported".

Something may be interfering with unencrypted traffic (have you got any firewall or antivirus installed - try disabling it, perhaps a browser plug in might be causing it).  Have you tried a different browser like Chrome or Firefox?

Sounds like maybe IE Enhanced Security Configuration.  Why you want to browse from a Server install anyway?

I just spotted you mentioned VMWare player.  Have you installed the VMWare guest components?

Hi there, thanks so much for your help.

Yes, enhanced security is off.  Note that the same problem occurs when I try to use Curl, or even telnet to these sites and manually perform a HTTP/GET from within the guest.  It just times out.

The current system is Hyper-V and was built on it - no VMware tools are or have-been installed on the guest OS.

Things tried today were to hard-set the host and guests' IP settings (rather than Reserved DHCP). - It didn't work.
Also tried disabling the port 80 forward ("virtual server") on the router.  It didn't help either.
Note that When I set the host machine to use wifi tethered to my mobile - access was normal.
when I use WIFI to connect to my Orcon router however, the problem occurred also.
Oh.  I'm using win2012 because I'm testing a server-class Application.

Next I may need to take to host to some other network, or start network sniffing.

Did you get to the bottom of this?  Curious what it was...

No, I didn't.  Though literature suggests it may be somehow related to IP fragmenting and MTU. 

I've been a bit busy at work, and will pick it up again when I get a chance.

Have a look at this article and verify if your MTU is 1500 bytes.  If it is, try reducing it to 1400 and see if the problem remains.  This might very well be an MTU squeeze.
