@olivierlambert Thanks! I did that and now it is just works.

Thanks for the help!

Wow - you guys where right. I had a Raspberry pi running with that address on my network. Sorry for the inconvenience and thanks for your help.

@jedimarcus maybe I found the error. I ran showmount -e 192.168.99.1
on my XCP-NG host and not on my XO VM. So I guess that this is the issue?

However, NFS server (TrueNAS 192.168.99.1/30) is directly connected (no switch inbetween) to my XCP-NG host (192.168.99.2/30) on eth1.

This might be a stupid question but, how should I add the NIC to my XO VM?

If I add/create eth1 to the XO VM what IP should I assign to it?

Because both XCP-NG and TrueNAS are directly connected. I guess that giving the XO VM the IP of 192.168.99.2 will conflict with XCP-NG's IP? Or are there something that I'm totally missing here? ... there probably is

Once again, thanks for your help I really appreciate it!

@jedimarcus - thanks for your reply. No jumbo frames

I have a NFS share that I have tried to add as a remote. I can add it and it stays as enabled but with a red warning icon besides and in the log I have the error below.

I'm running the community edition (build from source) of XO (xo-server 5.76.0) and (xo-web 5.78.1). I have two other NFS shares (ISO SR and a NFS SR) on this XO that works fine.

XO is running on a Debian 10 VM with the nfs-common package installed.

Any idea of what cause the error?

@jedimarcus Okay - and once again. Thanks for your help.

@jedimarcus By the way, my pfSense box has an intel 4x1Gb ethernet card. Would it be preferred/best practice to connect one of the pfSense NICs directly to an available NIC on my XCP-NG host and then assign this specific NIC to the exposed VMs? Or shouldn't I bother?

Thanks

@jedimarcus Thanks for your reply. Yes, you answer my question. I don't need to physical separated hosts VLAN is sufficient.

Thanks a lot for taken your time to answer my questions.

I'm a homelab'er enjoying learning and tinkering with networking and servers, and still learning a lot so please bear over with my trivial question.

Now the time has come where I might want to create some VMs that I would like to expose to the internet, if I do not put my whole network into a huge security risk.

My kids plays minecraft and I think it would a fun project to give them a server for them and their friends to join. Furthermore I would like to host a simpel webserver for a presentation site (wordpress).

My setup is as follows:

• pfSense (Dell Poweredge r210ii)
• XCP-NG host (Dell Poweredge r630)
• Truenas (Dell Poweredge 720xd)

However, before I proceed my project I have the following question/considerations:
What I understand is that I should create a DMZ for servers exposed to the internet and that these servers should be on a separat physical network.

So I guess that having the server VMs on a separated VLAN in XCP-NG is not secure enough? Or would you consider having the server VMs on the same XCP-NG host secure enough as long as their NIC are separated on VLANS? Or should I purchase another host for the exposed servers? Or is it even the recommendation that I acutally get another WAN connection into my home to compeletely separate the networks?

I understand that nothing is 100% secure but would you please share your thoughts and considerations on exposing servers as a homelab'er provides a significant security risk? Is this something other homelab'ers do or is hosting servers only a thing established and professional companies should do?

I know that this question could be posted on other forums but I thought that as I'm running XCP-NG I might as well ask here.

Thanks in advance for comments and replies.

I found the solution. I had to press enter during the boot to boot into the "CD-ROM drive".

I'm sorry for this novel question, but have trouble finding a solution for this issue.

I have created a Windows 10 VM in XO but when it boots for the first time it boots directly into the UEFI Interactive Shell.

I have tried to change boot firmware to bios and uefi. I have also tried to delete the VM and recreated it using bios boot option in the setup screen. But without any luck.

Any help is highly appreciated.

I'm running XCP-NG 8.2 on a Dell r630.
