No Internet on HCI-1 and HCI-2 (please help)

[askaresh]

Hi Frank,
I am running a hyper-V host where i am hosting the lab. I am not sure what details to provide here for the DC/RRAS to talk to the internet using external network.
scriptArgumentList = @('Ext', 'aMGMT', '192.168.0.241/30', '192.168.0.1', '8.8.8.8')

My Wifi router has the following range: (192.168.0.1/24)

The challenge is that the DC with the above internet is working. However, on the HCI-1 and HCI-2 the ping to ibm.com is not working. The internet ISP router doesn't have the capability for the creation of an additional subnet. Can you please provide some workaround of solution to get past this. A big thanks for the awesome vidoes and repo!

Hi @askaresh,
is .241 on this network free?
1st : I suggest to make the DHCP range of your router smaller e.g. DHCP End address: 192.168.0.250
Then you could give the DC/RRAS server the .251 IP address on this network. Also note the subnet range is a /24 for your 255.255.255.0 Local Network subnet mask.

2nd: try this argument:
scriptArgumentList = @('Ext', 'aMGMT', '192.168.0.251/24', '192.168.0.1', '8.8.8.8')

Thanks aton for your response. I managed to follow your recommendation: (Ensured 251 address is not in use)

and added this - scriptArgumentList = @('Ext', 'aMGMT', '192.168.0.251/24', '192.168.0.1', '8.8.8.8')

The result is the same DC - Internet works HCI-1 - request time out and HCI-2 request time. Although all three are able to ICMP each other.

ok. It is probably due to the fact that your network (your router) uses the same IP subnet range as the internal Azure Local (defined in 2_UnattendSettings.psd1) network (192.168.0.0/24) -> i.e. no routing will be done.
You have 2 options -
a) either change the IP range on your router....probably too heavy I would not do that.
b) change the IP addresses in the internal Azure Local network which is defined in the 2_UnattendSettings.psd1 file
see below.

hth,
B

e.g. to like (instead of using 192.168.0.x -> 192.168.10.x) - or something else just not use .192.168.0.x

@bfrankMS still the same outcome i am putting in all the screenshots and code for your reference:

00-hci-1 (ICMP works for HCI2 and DC1. But no internet)

00-dc-1 (ICMP works for HCI2 and HCI1. Internet works too - Tried 2022, 2016 Servers too)

Some side observations on WAC: (Havent reached this phase yet)
The script downloads the msi installer if I click in the UI:

Noticed a fresh installers file name is this - WindowsAdminCenter2410.msi

Please let me know what else can i try? Thanks a ton!

While awaiting your response performed some troubleshooting. It seems the issue is with the NAT.

00-DC-1
Blank when running the command:
PS C:\Users\Administrator> netsh routing ip nat show interface

This tells me there is no NAT no wonder Internet is not working on HCI-1 and HCI-2.

Re-created the NAT Manually (Now it shows)
PS C:\Users\Administrator> Get-NetAdapter

Name InterfaceDescription ifIndex Status MacAddress LinkSpeed

---

Ext Microsoft Hyper-V Network Adapter #2 5 Up 00-15-5D-00-37-92 1 Gbps
aMGMT Microsoft Hyper-V Network Adapter 4 Up 00-15-5D-00-37-9B 10 Gbps

PS C:\Users\Administrator> netsh routing ip nat install

PS C:\Users\Administrator> netsh routing ip nat add interface name="Ext" mode=FULL

PS C:\Users\Administrator> netsh routing ip nat add interface name="aMGMT" mode=PRIVATE

PS C:\Users\Administrator> netsh routing ip nat show interface
NAT aMGMT Configuration

Mode : Private Interface

NAT Ext Configuration

Mode : Address and Port Translation

Now its showing the details.

After the above is showing then when i do ping google.com it works from the HCI and DC nodes. Now the question is what causing this?

Under Step_PrepareAdminBox
I can see the log exist

NAT configuration

$netshFile = @"
pushd routing ip nat
uninstall
install
set global tcptimeoutmins=1440 udptimeoutmins=1 loglevel=ERROR
add interface name="EXTERNAL" mode=FULL
add interface name="INTERNAL" mode=PRIVATE
popd
"@

$netshFile = $netshFile -replace "EXTERNAL",$externalAdapterName
$netshFile = $netshFile -replace "INTERNAL",$internalAdapterName

Hi, Yeah, Good troubleshooting - others have seen something similar I.e. that the RRas config Was not done successfully. It might be a timing thing. Unfortunately I was never able to reproduce. If you find out what is causing this let me know. Thx B Gesendet von Outlook für Android<https://aka.ms/AAb9ysg>
